Peanuts, Boiled, Vietnamese (Đậu Phộng Luộc)

Đậu phộng luộc in the south, lạc luộc in the north — the same dish under two dialect names, and which one somebody says tells you which half of the country they are from.

Raw peanuts simmered in salted water until tender and nothing else at all. It is above all a drinking snack — the thing on the table with beer, among friends, at the informal end of an evening.

⭐ Which is exactly the seat boiled peanuts occupied at Charlie’s in Beaufort. It is remarkable how consistently this food ends up next to a drink: something about needing both hands, generating a pile of shells and taking a long time to eat makes it a conversation food everywhere it exists.

Ingredients

• 1 lb raw peanuts in the shell, green if you can get them
• 2-3 tbsp kosher salt
• Water to cover by 2 inches

Directions

Key ingredients

Salt

1. Rinse and soak — Wash the peanuts. Dried raw peanuts want an overnight soak; green peanuts go straight in.
2. Salt the water — Peanuts, salt and water into the pot. The salt level here is modest by Southern standards — this is a clean, straightforwardly salty peanut, not a heavily seasoned one.
3. Keep them under the water — Peanuts float, all of them, the whole time, and the ones on top do not cook. Weigh them down with a plate, a heavy lid or a steamer basket. An unweighted pot gives you a batch that is one third done, one third close and one third raw, and there is no fixing it afterwards. Top up with BOILING water as the level drops — cold water stalls the pot.
4. Simmer 45-60 minutes — Bring to a boil, then simmer. Green peanuts are quick. The Vietnamese texture is tender but still holding together — closer to the Japanese target than the Southern one.
5. The steep is not optional — When the kernels go creamy, turn the heat OFF and leave the peanuts in the liquid — one hour minimum, until the pot reaches room temperature is better, overnight is best. Salt diffuses through shell, skin and kernel slowly, and most of the seasoning arrives after the heat stops. A batch tasted straight off the fire always seems under-salted; the same batch four hours later is right. This is why adding salt at the end of the boil is nearly always a mistake — you have not tasted the finished product yet.
6. Serve warm — Pile them in a bowl with something for the shells, and open the beer. That is the entire serving suggestion and it is the correct one.

Notes

On the two names. Đậu phộng is the southern word for peanut and lạc the northern one; luộc means boiled in both. Worth knowing which to use depending on who you are talking to.

Peanuts in Vietnamese cooking go much further than this — crushed over noodles, in dipping sauces, in summer rolls — but boiled in salt water is the plainest thing that happens to them and one of the best.

A common variation is to boil them with a little jicama or sugar cane in the water for a faint sweetness underneath the salt.

Keeping them. Boiled peanuts are a wet, cooked, LOW-ACID food with no acid and no ferment — they are not a pickle and nothing in them preserves them. Refrigerate within two hours of the pot coming off the heat and eat within about four days, stored in their brine. They freeze extremely well in their liquid. To can them you need a PRESSURE canner and the tested process — never a boiling-water bath, and never an Instant Pot, which is a pressure cooker and not a pressure canner.
