Peanuts, Boiled, Chinese Spicy Brine (香辣卤汁花生)

The chilli version of the master-brine peanut — 香辣味, xiānglà wèi, ‘fragrant-spicy’. One of the two bags on my counter is the five-spice and the other is this, and the only difference in the ingredient list is that this one has chilli pepper in it.

It is a genuinely different eating experience from Cajun boiled peanuts even though both are ‘spicy boiled peanuts’, because the heat sits on top of a sweet, aromatic, soy-dark base rather than a salty seafood-boil one. Dried chillies and Sichuan peppercorn give you heat and a numbing tingle that nothing in the Southern repertoire does.

Ingredients

• 1 lb raw peanuts in the shell
• 3 tbsp kosher salt
• 8-12 dried red chillies, more to taste
• 1 tbsp Sichuan peppercorns
• 3 whole star anise
• 1 cinnamon stick or cassia bark
• 3 bay leaves
• 1 tbsp chilli bean paste (doubanjiang), optional
• 2 tbsp light soy sauce
• 1 tbsp dark soy sauce
• 1 tbsp rock sugar or brown sugar
• 4 slices fresh ginger
• 4 cloves garlic, smashed
• Water to cover by 2 inches

Directions

Key ingredients

Salt Soy Sauce

1. Rinse and crack — Wash the peanuts, and pinch each shell open slightly at the seam if you have the patience — it speeds the brine’s route to the kernel considerably.
2. Toast the dry spices — Dry-toast the chillies and Sichuan peppercorns in the empty pot over medium heat for about a minute, until they smell strongly. This is worth the sixty seconds — it wakes up both the capsaicin and the numbing hydroxy-alpha-sanshool in a way that dropping them into cold water does not.
3. Build the brine — Add everything else except the peanuts, plus the water. Boil, then simmer 10 minutes.
4. Add the peanuts and weigh them down — In they go.
5. 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.
6. Simmer — Gentle simmer, covered — 40 minutes for the firm Chinese texture, up to 3 hours for creamy.
7. 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.
8. A warning about the overnight steep — Capsaicin keeps migrating into the peanuts while they sit. A batch that is pleasant at midnight can be genuinely hot by morning. Under-chilli deliberately if you are steeping overnight, and pull the chillies out once you are happy.

Notes

Where this comes from. Reconstructed from Chinese home recipes and from the back of a commercial bag of 卤汁花生（香辣味）— Fortune brand, Product of PRC. Its declared ingredients are: peanuts (in-shell), water, salt, sugar, chilli pepper, spices, monosodium glutamate, disodium 5’-ribonucleotides, sodium erythorbate, natural flavor.

Nutrition off that bag, per 100 g: 352 kcal, fat 27.4 g, sodium 654 mg, carbohydrate 11.2 g, protein 15.7 g. The sodium is the headline — a third of a day’s allowance in 100 g, and the bag is 306 g and cheerfully calls itself one serving.

Add MSG if you want the bag flavour. I am not squeamish about it and the commercial version leans on it hard. A teaspoon of MSG in the brine gets you noticeably closer to what is in the packet than any amount of extra spice will.

The sugar matters more than it looks. No Southern boiled peanut has ever had sugar in it; every 卤 brine does. That trace of sweetness under the salt is the single most characteristic thing about the Chinese version.

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.
