Homemade Burger Sauce for Full GAPS

Homemade burger sauce adds a creamy, tangy finish to a simple Full GAPS burger. Mayonnaise and tomato ketchup make the base, with finely diced fermented pickle, yellow mustard, fresh lime, garlic and onion mixed through it. The sauce turns a soft orange-pink color, with small pickle and onion pieces in every spoonful.

You can mix it with a fork or whisk in about five minutes once the ingredients are ready. Have the mayonnaise made and the ketchup and pickles finished before sauce day. Their preparation is separate from this quick mixing step.

I homeschool before leaving for second-shift work, and I prepare lunch and dinner before I go unless they are already made. With six children, knowing which parts of a meal can be ready beforehand matters. This recipe puts the longer kitchen jobs in the homemade components, then brings them together in one bowl when you need the sauce.

The finished bowl should be evenly creamy, with the small vegetable pieces distributed throughout. It has a fresh lime scent and a noticeable garlic flavor. Keep the sauce cool and spoon it onto the burger after cooking, so the cold-pressed avocado oil in the mayonnaise stays out of the cooking pan.

What You Need

One cup of homemade mayonnaise: Use the avocado-oil version of homemade Full GAPS mayonnaise. Finish the emulsion before measuring the cup. It should be thick and evenly creamy, with the oil incorporated. The burger sauce starts with ready mayonnaise; it does not make a new mayonnaise emulsion in this bowl.

One-quarter cup of fermented ketchup: Measure the completed homemade fermented tomato ketchup, after its vinegar has been stirred in and the jar has moved to the refrigerator. It should be thick and spoonable. The cloves and allspice in that condiment bring a little background spice to the burger sauce.

One small fermented pickle: Use a finished fermented dill pickle. Lift it from the brine, let the excess liquid drain and dice it finely. Small pieces spread through the sauce more easily than thick cucumber chunks. There is no extra measure of pickle brine in this recipe.

Two teaspoons of prepared yellow mustard: Choose plain prepared mustard made without added sugar or starch. Mustard seed, vinegar, water, salt and turmeric are the kinds of ingredients to look for. Use prepared yellow mustard for the texture and flavor of this version.

Two fresh limes: Juice both limes and remove the seeds. Their size and juiciness can vary, so the finished sauce may be a little looser in one batch than another. The lime gives a sharper, fresher finish alongside the mayonnaise and ketchup.

Four garlic cloves and half a small onion: Crush the peeled garlic and finely dice the onion. The onion stays raw, so small, evenly cut pieces make a difference when you spoon the sauce over a burger. Four cloves give the sauce a definite garlic flavor.

Cider vinegar, mineral salt and optional cayenne: The card lists one teaspoon each of raw apple cider vinegar and mineral salt, both to taste, plus one-quarter teaspoon of pure cayenne if you want heat. Mix the prepared components first, then season. The mayonnaise, ketchup and fermented pickle already bring salt and acidity with them.

Where This Fits In GAPS

This is a Full GAPS condiment after its ingredients, including raw vegetables, fermented foods and the mayonnaise ingredients, have been introduced. It contains raw onion, garlic, lime juice and a completed cucumber ferment. Keep it with your Full GAPS recipes rather than treating it as an early Intro sauce.

Dr. Natasha’s 2020 guidance includes avocado oil and other suitable cold-pressed oils for use without heating. That is why this sauce is stirred cold and added to ready food. The homemade mayonnaise supplies the oil and egg yolks; the ketchup, pickle and seasonings supply the rest of the flavor.

The ketchup starter matters if you are avoiding dairy. The linked ketchup can use homemade cultured whey or raw fermented vegetable brine. A whey batch contains a dairy ingredient. Choose the vegetable-brine preparation when that is the version that fits your household, then measure the same quarter cup of finished ketchup for this sauce.

The mayonnaise contains eggs. This recipe also contains vegetables and plant ingredients, so it does not fit No-Plant GAPS. The dairy-free ketchup choice changes the starter in that component while keeping the measured amounts in this burger sauce the same.

How To Make Homemade Burger Sauce

1. Get The Components Ready

Measure the completed mayonnaise and ketchup into a glass mixing bowl with room to stir. Finely dice the drained pickle and onion, crush the garlic and juice the limes. Set out the mustard, cider vinegar, salt and optional cayenne.

Doing the chopping first makes the mixing straightforward. You should have small pickle and onion pieces ready to fold through the creamy base. Large pieces left on the cutting board will make the sauce uneven, with one spoonful mostly mayonnaise and another mostly onion.

2. Mix The Creamy Base

Stir the mayonnaise, ketchup, mustard and fresh lime juice together with a fork or whisk. Scrape across the bottom and around the sides of the bowl, where a pocket of white mayonnaise can stay unmixed.

At first, you will see red ketchup and white mayonnaise streaks. Keep stirring until the base is one even orange-pink color. It should look creamy and glossy. The lime juice loosens the mayonnaise, so the finished sauce will not have exactly the same stiffness as the original jar of mayo.

3. Fold In The Pickle, Onion And Garlic

Add the finely diced pickle, onion and crushed garlic. Stir until the pieces are distributed through the bowl. You are looking for a creamy sauce with small vegetable pieces, not a completely smooth purée.

Add the cider vinegar and mineral salt to taste, using the measured amounts in the card as your guide. Stir and taste after each addition so you can notice what the already-seasoned components contribute. Add the optional cayenne if you want a warmer finish, then mix it through thoroughly.

A fork or whisk is enough for this method. There is no need to move the sauce into a blender to remove the pickle and onion texture. Keep those small pieces in the finished bowl.

4. Serve Or Refrigerate

Spoon the sauce onto cooked burgers just before serving, or put a small bowl beside vegetables for dipping. The garlic and lime are noticeable, so serve the sauce where you can choose how much to add to each plate.

Transfer the remaining sauce to a clean, covered glass jar and refrigerate it. Label the jar with the mixing date. Keep the mayonnaise, ketchup and pickle preparation dates in mind as well; combining them does not make older components newly prepared.

Storage And Advance Preparation

Keep the sauce covered and refrigerated between uses. Use a clean utensil to take out the portion you need, then return the jar to the refrigerator. A serving bowl on the table can hold that meal’s portion while the larger jar stays cold.

This is a mixed condiment made with completed ferments. It does not have a separate counter-fermentation step. Make the ketchup and pickles ahead of time, prepare the mayonnaise, and bring them together when those ingredients are ready to use.

The five-minute preparation time assumes those components are finished and ready. It does not include making mayonnaise, cooling pickle brine or waiting for a ferment. If you are starting those from scratch, follow their separate recipes first.

The card makes one batch. Finished volume depends partly on the size of the limes, onion and pickle. If you need a specific quantity for a meal plan, measure the completed sauce. For a doubled batch, use a bowl and covered storage jars with room for twice the mixture.

Frequently Asked Questions

Is This The Same As Barbecue Sauce?

This is a creamy mayonnaise-and-ketchup burger sauce. It is stirred cold and spooned onto ready food. It is not the kind of tomato-based sauce you simmer or brush onto meat while it cooks.

Can I Use Mustard Powder?

This recipe calls for two teaspoons of prepared yellow mustard. Mustard powder is a concentrated dry ingredient, so it is not the same measure or texture. Keep the prepared mustard amount here instead of making an unmeasured powder substitution.

Why Does The Sauce Have Small Pieces?

They are the finely diced pickle and onion. Those pieces belong in this sauce. Dice them small enough to spread through the bowl, and crush the garlic so you do not leave large garlic pieces in one serving.

Can I Make It Without Cayenne?

Yes. Cayenne is optional in the measured recipe. Leave it out for a milder finish while keeping the mayonnaise, ketchup, pickle, mustard, lime, garlic and onion amounts the same.

Is It Dairy-Free?

That depends on the ketchup you use. The avocado-oil mayonnaise has no dairy ingredient, but ketchup cultured with whey does. The linked ketchup’s fermented vegetable-brine option gives you a preparation without a dairy starter. Check that component before describing the finished burger sauce as dairy-free.

Recommended Equipment

A glass mixing bowl, fork or whisk, measuring cups and spoons, a small knife, a cutting board and a covered glass storage jar handle this recipe. Use a bowl with enough space to scrape and fold the sauce without pushing it over the rim.

The homemade components have their own equipment and preparation methods in the linked recipes. For the burger sauce itself, the useful tool is the fork or whisk already in your hand. You are combining finished ingredients, not making the mayonnaise or fermenting the vegetables again.
