Pickled Jalapeños
A refrigerator pickle of jalapeño rounds in a warm spirit and cider vinegar brine. Ready in 24 hours. Best crunch in the first 3 to 4 weeks.
Why the second revision
First revision → second revisionReplaced the archive method with the method that was cooked. The brine is now warm, not boiling: the pour is at 60–70 °C, so the rounds stay crisp. The vinegar is a 2:1 blend of spirit vinegar and apple cider vinegar. Coriander seed, cumin seed and peppercorns are toasted first. Salt and sugar are weighed, and salt is set at about 3.6 % of the liquid. The batch is 680 g of jalapeños. The brine is 1,350 ml, because 680 g of rounds needed that volume to cover. The spices in the brine were doubled with the liquid. No calcium chloride.

Put on nitrile gloves. Water does not remove capsaicin from skin.

Cut the jalapeños into rounds of 3–4 mm on a mandoline. Discard the stems.
Most of the heat is in the pale ribs. Keep them for full heat. Remove them for a milder pickle.
Tool mandoline -
Pack the rounds into clean jars with the garlic and the bay leaves. Do not crush the rounds.
Divide the garlic and the bay leaves by the size of each jar.

Toast the peppercorns, coriander seed and cumin seed in a dry pan on medium heat until fragrant.
Stop before they go dark. Burnt seeds make the brine bitter.

Notes
5Untested ideas carried over from the original note:
- 2½ tsp sesame oil in the brine
- Cauliflower florets and green beans for colour and variety
- Jicama sticks for crunch
- White wine in place of the water
- Cumin and chilli powder in the brine
- Coconut sugar instead of white sugar
Scale the brine up if you add vegetables — everything has to stay submerged.
More sugar gives a milder pickle, less keeps it spicier.
Keeps in the refrigerator for up to 2 months.
Jalapeños are more than 90 % water. The first batch releases that water into the brine, so a used brine holds about half of its starting acid and less salt.
Fresh rounds dilute it again. This reduces the acid margin that preserves the pickle. The new rounds also stay under-seasoned.
The old rounds and the new rounds are also at different ages. The older rounds are softer, and you cannot tell them apart in the jar.
Put new rounds in fresh brine in a separate jar. To reuse the jar, move the old rounds to a small container with enough of their brine to cover them. Then wash the jar.
The first calculation for 680 g of jalapeños gave 675 ml of brine. That did not fill the jars. The cook made two times that volume.
Plan about 2 ml of brine for each 1 g of whole jalapeño. Loose-packed rounds leave more space in a jar than the earlier scaling allowed for.

The parts
6Jalapeño, cut into rounds of 3–4 mm
The thing you pickle. Thin rounds take up the brine fast and stay crisp.
540 ml white spirit vinegar (about 5%) and 270 ml apple cider vinegar, a 2:1 blend
Preserves the pickle and gives the sour taste. The vinegar is 810 ml of the 1,350 ml liquid, which is 60%. The vinegar-to-water ratio is 810:540, which is 1.5:1 (3:2).
- !SAFETY Swap: Spirit vinegar at 10% acidity in place of the 5% spirit vinegarMeasure 540 ml of the 10% vinegar. Then replace 140–220 ml of it with water. Keep the 270 ml apple cider vinegar. Do not reduce the vinegar further. A lower acid share reduces the margin that preserves the pickle.
540 ml water
Softens the vinegar so the pickle is sour but not harsh.
48 g non-iodised sea salt, weighed (about 3.6% of the 1,350 ml liquid)
Seasons the rounds. The rounds take their salt from the brine, so the brine concentration sets the seasoning.
- !SAFETY Swap: Any non-iodised salt, flake (Maldon) or fine, at the same weight: 48 g in 1,350 ml liquidWeigh it. Do not measure by volume: flake salt and fine salt differ by a factor of two by volume. When you scale, keep the salt at about 3.6% of the total liquid.
22 g sugar
Rounds off the vinegar and controls how hot the pickle tastes.
- Swap: More or less sugar. More sugar gives a milder pickle. Less sugar keeps it spicier. The record gives no amount for this change.
Garlic (5 cloves, crushed), bay leaf (3 leaves), black peppercorns (7 g), coriander seed (6 g), cumin seed (4 g), Mexican oregano (3 g, optional); the seeds toasted
Give the brine its savoury, warm flavour. Tannins from the bay leaves also help keep the rounds crisp.
The basic method
7- Put on gloves. Cut the jalapeños into rounds of 3–4 mm. Remove the pale ribs for a milder pickle.
- Pack the rounds into clean jars with the garlic and the bay leaves.
- Toast the peppercorns, coriander seed and cumin seed in a dry pan for 1–2 min, until fragrant. Do not let them go dark.
- Put the vinegars, water, salt, sugar and spices in a non-reactive pan. Heat to a gentle simmer and stir until the salt and sugar dissolve.
- Let the brine cool to 60–70 °C. Pour it over the rounds until each jar is full.
- Keep every round under the brine. Let the jars cool uncovered for 20 min. Then close them and put them in the fridge.
- Wait 24 h before you eat them. Eat them within 3 to 4 weeks for the best crunch.
What the full recipe adds
The full recipe explains why the brine is poured at 60–70 °C and not boiling: above about 80 °C the pectin in the cell walls breaks down and the rounds go soft, while 50–70 °C lets an enzyme in the pepper firm the pectin. It gives the brine volume as about 2 ml for each 1 g of whole jalapeño, because loose rounds leave more space in a jar than expected. It explains how to scale the salt from the total liquid. It warns not to top up an old jar with fresh rounds, because the used brine holds about half of its starting acid. It says the pickle keeps up to 2 months in the fridge. These points protect crunch, seasoning and the acid margin.
The science
2What is actually happening in the dish, and why the techniques work.
The snap of a pickled round comes from the cell walls. Pectin holds the cells together in the middle lamella, the layer between cells.
Heat is the first threat. Above about 80 °C the cell walls lose their structure fast and the pectin goes into solution. A boiling pour cooks the rounds soft. A pour at 60–70 °C lets the brine in without that damage.
The warm pour can also help. Pectin methylesterase, an enzyme in the pepper, works best near 50–70 °C. It changes pectin so the calcium already in the pepper can link the chains. Linked pectin is firmer.
Enzymes are the second threat. Polygalacturonase and microbial pectinases cut the pectin chains over the following weeks. Tannins from the bay leaves slow them. The refrigerator slows them more.
Added calcium chloride is the strongest lever. This version does not use it. Without it, eat the pickle in the first 3 to 4 weeks for the best crunch.
The rounds take their salt from the brine by osmosis. So the salt concentration of the brine sets the seasoning, not the weight of chilli.
This version uses 48 g of salt in 1,350 ml of liquid. That is about 3.6 %.
When you scale the batch, calculate the salt from the total liquid at 3.6 %. Weigh it. Flake salt and fine salt differ by a factor of two by volume.
If you make the brine in two pans, weigh the total salt first. Then divide it. Otherwise the jars are seasoned differently.
Revisions
2A revision is written when the dish changes, and the version it replaces is kept. Beside each is a sentence describing what the dish became — the part a cook can act on.
Replaced the archive method with the method that was cooked. The brine is now warm, not boiling: the pour is at 60–70 °C, so the rounds stay crisp. The vinegar is a 2:1 blend of spirit vinegar and apple cider vinegar. Coriander seed, cumin seed and peppercorns are toasted first. Salt and sugar are weighed, and salt is set at about 3.6 % of the liquid. The batch is 680 g of jalapeños. The brine is 1,350 ml, because 680 g of rounds needed that volume to cover. The spices in the brine were doubled with the liquid. No calcium chloride.
