When to Pick Shishito Peppers and Why One in Ten Is Hot

The size you are aiming for

Shishitos are eaten thoroughly immature. The pod you want is two to three and a half inches (5 to 9 cm) long, slender, wrinkled along its length, glossy and a clear mid green, and thin enough in the wall that it gives slightly when you squeeze it instead of feeling solid. That state arrives about two weeks after the flower opens and holds for four or five days.

After that the wall firms, the skin thickens, the seeds inside go from a soft mass to a papery core, and the flavor sharpens. None of that reverses. If you are unsure whether a pod is ready, pick it: an extra day gains you almost no size and costs you the tenderness that is the entire point of the crop.

Pods hide. A large share of the ones that go tough are hanging directly under a leaf in the middle of the bush. Crouch and look up through the plant once at the end of every pick.

Why the interval is the whole technique

Go over the plant every two or three days through the main season and it will keep flowering for months. Go over it once a week and two things happen at once. Half of what you find is already past its best, and more importantly the plant reads the maturing pods as finished seed and slows new flower production within days.

Three or four mature pods left hanging is enough to bring a plant close to a standstill for two or three weeks. This is far and away the commonest reason a shishito that started strongly stops producing in midsummer, and people almost always blame the weather for it. The fix is immediate and it works more than once in a season.

1. Strip every mature pod at once Go through a stalled plant and take off everything full sized, tough or coloring, whether or not you want to eat it. Compost the unusable ones. You are removing a signal, not salvaging a crop.
2. Water and feed the same day Give it a full watering and a potassium weighted feed at normal strength so there is something for it to restart on.
3. Expect flower buds in about ten days New buds appear within seven to ten days, and pickable pods follow roughly two weeks after that. The recovery is reliable if the plant is otherwise healthy.
4. Fix an interval you can actually keep Two named days a week works far better than an intention to pick often. Consistency does more for total yield on this crop than any amount of feeding.

If you are away for two weeks, pick the plant completely bare before you go, including pods barely worth taking. You lose far less that way than by returning to a plant that has shut down.

The hot ones: where they come from

Roughly one shishito in ten comes out unexpectedly hot in a crop that is otherwise mild, and there is no way to tell which one by looking at it. This is normal and expected in the crop rather than a fault in your plant, a mislabelled seedling or a disease.

What you control is the proportion. Stress pushes it up, sometimes to one in five or worse. A long dry spell, a container that went bone dry while you were away, a stretch of days over 95F (35C), or a plant carrying more pods than its roots can supply all raise the odds, and the pods most likely to bite are the ones that grew through the worst of it and the ones that hung on the plant longest.

Practically, that means two things. Keep the water steady, which is the only real control. And if the plant has had a hard week, taste a small raw sliver before cooking a whole panful for other people.

Heat in a pod is not evenly spread. It concentrates near the seeds and the pale ribs inside, so a sliver of wall alone can taste mild while the whole pod is not.

Cutting pods off without breaking the plant

The pod stalk is fibrous and firmly attached, and the branch behind it snaps easily. Pulling costs a fork often enough that snips should simply live in the harvest basket for this crop.

1. Hold the branch behind the pod Support the branch with your free hand so the cutting hand is not levering against unsupported brittle wood.
2. Cut the stalk with a short stub left on Snip about a quarter inch (6 mm) above the pod. The stub keeps the pod sealed and slows softening in storage.
3. Work outside in, then look up Take the obvious outer pods, then part the foliage and search the interior. Finish by looking up through the plant from below.
4. Pick dry Pods taken in the morning once the dew has gone keep better than pods picked wet, and wet foliage spreads leaf spot on the hands and snips.

Yield, keeping them and the end of the season

A well kept plant hands over sixty to a hundred pods across a three to four month season, which is why two or three plants overwhelm most households. People plant six, cannot keep up with the picking, and then wonder why the plants stalled at the height of the season.

Unwashed pods keep about a week in a bag in the refrigerator and are better if picked dry. They freeze whole and raw without blanching, which is the honest answer to a glut, though they come out soft and belong in cooked dishes afterwards. Once nights drop below 50F (10C) the plant stops filling pods, so pick everything left at whatever size it has reached and let a handful color indoors.

Keep a running tally of pods per plant per week. It is the most informative number in this crop, because it shows exactly when the plant stalled and how fast clearing it brought the flowers back.
