Creamy Mashed New Potatoes for Coming Off GAPS

These skin-on mashed new potatoes are soft and creamy, with butter worked through the warm potatoes and a little tang from homemade sour cream. You mash them by hand, leaving small flecks of tender skin in the finished dish.

This is a Coming Off GAPS recipe, for when new potatoes and the dairy foods used here have already been introduced and tolerated. This recipe serves six. That is the household yield, not the amount to eat when first trying potatoes.

Choose the potatoes and dairy

Use 3 pounds of young, new-season Yukon Gold potatoes. Scrub them well under running water, leave the skins on and cut them into roughly 2-inch pieces. Keeping the pieces similar in size helps their centers soften at about the same time.

Measure ½ cup raw whole milk, 8 tablespoons unsalted butter and ¼ cup finished homemade cultured sour cream for the base batch. Eight tablespoons of butter is ½ cup. Have the dairy measured and ready while the potatoes boil, keeping it refrigerated until needed.

The kefir-cultured sour cream is a separate recipe. Make and chill that component beforehand, then measure a quarter cup of the finished cream. You are adding prepared sour cream to these potatoes, not cream and starter that still need fermenting.

Use this version only once raw milk and the other dairy foods are already tolerated separately. The dairy introduction progresses through fermented foods and cheese before raw milk. Trying the whole creamy potato dish is not a way to introduce several new foods at once.

Measure the salt for the kind you have

The base recipe uses 1 tablespoon coarse Celtic sea salt. If you are using fine salt, begin with half that volume: 1½ teaspoons for the base batch. Mash and taste before adding more. Crystal size affects how much salt fits in a spoon, so the smaller starting amount matters.

The card gives the coarse-salt amount and explains the fine-salt alternative as half the listed volume. When you double the card, the coarse-salt amount becomes 2 tablespoons, so the fine-salt starting amount becomes 1 tablespoon. Freshly ground black pepper is optional and goes in to taste at the end.

Boil, drain and mash

1. Bring the potatoes to a boil. Put the scrubbed, cut potatoes in a large stainless-steel or enameled pot and cover with water. Leave headroom above the water rather than filling the pot to its rim. Bring to a boil over high heat, then reduce to medium-high to maintain a steady boil.
2. Check a larger piece. Boil for about 15 to 20 minutes. Push a fork through the center of a larger piece. It should slide through without meeting a firm core, and the cut edge should yield. Continue cooking as needed until that check passes.
3. Drain well. Carefully drain the potatoes in a colander. Return them to the warm, empty pot off the heat. Let the visible surface moisture steam away briefly so it does not thin the mash.
4. Add the measured dairy and salt. Add the milk, butter, finished cultured sour cream and the listed coarse salt. If using fine salt, start with half the listed salt volume instead. Keep the pepper for the final tasting.
5. Mash by hand. Use a potato masher until no large potato pieces remain and the butter has melted into the mash. The skins will remain in small pieces. Stop once the texture is creamy rather than continuing to beat or blend it.
6. Taste and serve. Taste a small spoonful. Add optional black pepper and more salt only if needed, then serve warm. Use the serving controls to scale the ingredients for a larger batch.

The 35-minute plan includes 15 minutes of preparation and about 20 minutes of cooking. The actual time depends on the potato pieces, pot, stove and how quickly the water reaches a boil. Use the fork check rather than mashing potatoes that still have a firm center.

Keep the mash creamy

Drain the potatoes thoroughly before adding dairy. Water pooled in the pot would make the finished mash looser even though you measured the milk and sour cream correctly.

A hand masher gives you control over the texture. Work through the larger pieces, let the butter melt through the warm potatoes and stop when the mash is ready to serve. Long, vigorous mixing can make potatoes sticky. A blender is not needed for this method.

For a doubled batch, use a pot and colander large enough for all the potatoes and water. Larger quantities may take longer to heat. The cooking check stays the same: a fork must reach the middle of a larger piece without resistance.

Where this fits when coming off GAPS

Potatoes do not belong on the strict Introduction or Full GAPS Diet. New potatoes are among the early foods introduced when coming off GAPS. Most people follow the strict diet for at least two years, and at least six months of normal digestion comes before introducing foods outside it.

Introduce one food at a time. Start with a small amount, watch for returning symptoms for two to three days, then try another small portion after a few days if the earlier one was tolerated. Increase gradually rather than starting with a full dinner serving. Serve the starch with plenty of fat; the butter is part of this recipe.

Potatoes are nightshades. If nightshades have caused problems, potatoes are not the first one to introduce: tomato, eggplant and peppers come earlier in that introduction order. This potato-and-dairy recipe assumes those relevant steps and the separate dairy introductions are already settled.

Serving and storing

Serve the mash with a main dish and vegetables you already tolerate. The cilantro lime grilled shrimp is one separate main-course option. Make the potatoes close to serving time so you can bring them to the table while they are warm.

Refrigerate leftovers promptly in shallow, covered containers at 40°F (4°C) or below and use within three to four days. Refrigerate perishable food within two hours, or within one hour if it is above 90°F (32°C). Making the mash does not restart the storage life of older milk or sour cream, so use ingredients that are still within their own storage period.

Reheat a portion gently in a covered pan, stirring as needed, until it reaches 165°F (74°C) throughout. Check with a food thermometer. Stir gently rather than beating the potatoes repeatedly.

Questions before you begin

Can I use ordinary mature potatoes?

Use the new-season Yukon Golds specified here. New potatoes are the form named for this early Coming Off GAPS use; the recipe is not a general instruction to replace them with mature storage potatoes.

Do I need to peel them?

No. Scrub them thoroughly and keep the skins on. Cut them into roughly 2-inch pieces, then cook until the centers are tender. Small pieces of skin remain in the finished mash.

Can I make it before introducing raw milk?

Use this creamy version after raw milk, butter and the cultured sour cream have each been introduced and tolerated. Do not use the finished dish to test several unfamiliar ingredients together.

Why is my mash watery or sticky?

For watery mash, check that the potatoes were drained well before the dairy went in. For sticky mash, stop mixing once the large pieces are broken up and the butter is incorporated. Do not try to fix either problem by adding unmeasured dairy to this batch.

Equipment and transition help

You need a large stainless-steel or enameled pot, a colander, a knife and cutting board, measuring cups and spoons, a fork and a sturdy potato masher. A serving bowl and spoon finish the setup. A food thermometer is useful when reheating leftovers.
