Papa Seca substitute

Best substitute

Dehydrated or freeze-dried diced potato

Use the same amount by dry weight, toasted before use as the papa seca you are replacing

Best for carapulcra

Different taste

Dehydrated or freeze-dried diced potato from a camping or emergency-food supplier is the closest swap at one for one by dry weight, and you must toast it in a dry pan before use. Better still, make your own by boiling, cubing and drying potatoes, then pulsing them coarse. If you have to use fresh potato, cube it, boil it, then pan-toast the cubes hard, because the toasted flavour is the whole point.

Other papa seca substitutes

Ranked, with the exact amount to use

2Homemade dried potato
Close match
Use the same amount by dry weight, so about 1 kg fresh potato per 200 g papa seca
The genuinely correct substitute, since it is the same process on a domestic scale.
What changes
Best for
carapulcra, authentic Peruvian cooking, stews
Boil waxy yellow potatoes until just tender, cool, peel, cut into small cubes, then dry them in a low oven at around 70 C or a dehydrator until hard and rattling, which takes several hours. Pulse briefly in a food processor to crack rather than powder them, then toast in a dry pan. The result is very close indeed, marginally less intense than commercial papa seca because sun-drying does something an oven does not. It keeps for months in a jar and this is the route worth taking if you cook carapulcra more than once.
3Waxy potatoes, boiled then pan-toasted
Taste and texture differ
Use About 4 to 5 times the dry weight, so 1 kg fresh potato for every 200 g papa seca
The fresh-potato route, which works if you accept that the texture will change and you commit to the toasting step.
What changes
Best for
carapulcra, stews, weeknight versions
Cut waxy potatoes into one-centimetre cubes, boil until barely tender, drain, dry them well, then fry in a little oil over high heat until browned on several sides. The browning is doing the work that drying and toasting do for papa seca. The stew comes out softer, creamier and looser than a real carapulcra, which is thick and chewy, so add a spoonful of potato flakes near the end to firm up the sauce. Use waxy potatoes, never floury baking potatoes, which will collapse.
4Hominy or dried mote corn
Different taste
Use the same amount by dry weight, cooked until tender
A pantry item that matches the chewy, holds-its-shape quality papa seca brings to a long stew.
What changes
Best for
carapulcra, stews, soups, pork braises
Texturally this is a good match, since hominy stays chewy through an hour of simmering and gives the same satisfying resistance. Flavour-wise it is unambiguously corn, sweet and nutty and lime-treated, so your carapulcra becomes a corn and pork stew. That is a nice dish, but it is not the same dish, and the toasted-potato flavour that defines carapulcra will be absent. Choose this when texture matters more to you than authenticity.
5Dried cassava or dried yuca
Taste and texture differ
Use the same amount by dry weight, soaked and boiled until fully tender
Another dried tuber that survives long cooking and thickens the sauce as it goes.
What changes
Best for
carapulcra, stews, braises
Holds shape beautifully and releases starch to thicken the stew, which is genuinely useful. It is sweeter and more neutral than potato and noticeably more fibrous, giving a stringy rather than grainy bite. Soak it, discard the soaking water and boil it until completely soft, since cassava should never be eaten raw or undercooked. Toast it dry beforehand if you can, which adds a welcome nutty note.
6Potato flakes, for body only
Taste and texture differ
Use 3 to 4 tbsp flakes for every 100 g papa seca, added near the end
Not a substitute for the pieces, but the fastest way to get a stew with the right consistency.
What changes
Best for
thickening carapulcra, rescuing a thin stew, emergency versions
Papa seca thickens carapulcra as much as it fills it, and potato flakes deliver that thickening in two minutes. Toast the dry flakes in a pan first, which is a small trick that adds surprising depth. What you get is a thick, smooth, mashed-potato-textured stew with none of the chew, so this is best used alongside cubed toasted potato rather than on its own. Add it gradually off the heat, because it thickens fast and cannot be undone.

What is Papa Seca?

Papa Seca is Papa seca, sometimes sold as papas secas or simply Peruvian dried potato, is potato that has been boiled, peeled, sun-dried and then cracked into coarse yellow grains, and it is toasted in a dry pan before being simmered into carapulcra.

Cooking tips

Toasting is not optional, whatever you substitute. Papa seca is dry-toasted in a pan until it smells nutty and darkens before any liquid touches it, and that toasted flavour is the single thing that makes carapulcra taste like carapulcra. Toasting whatever you use matters more than which potato you chose.
Soak after toasting, not before. Cover the toasted grains with warm water for twenty to thirty minutes, then add them and their soaking water to the stew, since that water carries flavour. They will keep absorbing liquid as the stew simmers, so keep a jug of stock nearby.
Papa seca swells a great deal, roughly doubling or tripling in volume. If you are converting a recipe or eyeballing quantities, start with less than looks right or you will end up with a pan of paste rather than a stew.
It is a thickener as well as an ingredient. Carapulcra should be thick enough for a spoon to stand up in, and that comes from starch shed by the papa seca, so if you use a substitute that sheds less starch, expect to thicken the stew yourself.
Do not confuse papa seca with chuno. Chuno is raw potato freeze-dried in Andean frosts, soaked rather than toasted, and used in whole pieces in soups such as chairo. Substituting one for the other gives you the wrong flavour and the wrong texture.

Frequently asked questions

Can I just leave it out?

Not in carapulcra, where papa seca is the body, the thickening and the signature toasted flavour all at once. Without it you have a pork stew in aji panca sauce, which is pleasant but is a different dish. If you have no dried potato of any kind, boiled and hard-fried potato cubes plus a spoonful of potato flakes is the honest minimum.

What does papa seca taste like?

Toasty, nutty and faintly sweet, with a concentrated potato flavour quite unlike a fresh potato and a slightly grainy, chewy texture even after long simmering. People often compare the aroma while toasting to popcorn or roasted grain, which is a good sign that you are doing it right.

Can I use instant mashed potato instead?

Only as a thickener, and it is worth being clear about the difference. Instant mash gives you smooth starch with no structure, so the stew turns into a thick puree with pork in it. Toasting the flakes dry first improves the flavour considerably, but you still need something with bite alongside it.

Where can I buy papa seca?

Peruvian and Latin American grocers stock it in bags, labelled papa seca or papas secas, and online importers ship it internationally. It is shelf-stable for a year or more in a sealed jar in a dry cupboard, so buying several bags at once is sensible given how hard it is to find locally.

Is papa seca gluten free?

Yes, it is nothing but dried potato. The substitutes on this list are also naturally gluten free, though packaged dehydrated potato products sometimes contain additives, so check the label if that matters for you.
