Harvest timing and storage: picking at the right moment, keeping what you can't use

The difference between a good sauce and a great one is usually decided in the garden, in the last three weeks before you pick.

When each crop is actually ready

Crop	Ready when	The mistake
Habanero	Fully orange, twists off easily	Picking green — hot, tastes of nothing
Jalapeño (for chipotle)	Deep red, corked	Picking green, which is a different, lesser ingredient
Serrano	Firm and green	Waiting for red loses the grassy note verde needs
Cayenne	Fully red, slightly leathery	Picking green: dries grey and tastes flat
Marconi	Fully red, shoulder to tip	Green is just a mediocre bell
Paste tomato	Fully coloured, slight give	Refrigerating after picking
Tomatillo	Husk splits, fruit fills it	Picking by size — underripe is bitter and hard
Basil	Any time, before flowering	Letting flower spikes run; leaf turns bitter
Cilantro	Broad lower leaves, pre-bolt	Harvesting the ferny pre-bolt leaves
Onion	Tops fall over on their own	Bending tops over yourself — it shortens storage
Garlic	3–4 lower leaves brown, uppers green	Waiting too long; wrappers split and it won’t store
Carrot	Shoulder ~¾″ across	Leaving them in summer heat, which turns them bitter

Two rules that apply to everything

Cut, don’t pull. Pulling a pepper tears the branch and opens a wound that invites disease. Snips, every time.

Pick in the morning. Turgor is highest and field heat lowest. It genuinely affects how long a harvest holds before you process it.

Holding a harvest until you have a batch

Almost nobody gets 12 pounds of tomatoes on one day. You accumulate.

Freeze — the default, and the best one

• Chiles: whole, on a sheet tray, then bagged once solid. A year. Texture goes; for sauce that is irrelevant.
• Tomatoes: whole, washed and cored, straight into bags. Under warm water the skins slip off with no blanching at all.
• Roasted peppers: char, peel, freeze in their own juices. Romesco becomes a fifteen-minute job in February.
• Herbs: as pesto or zhoug in ice-cube trays rather than as loose leaf, which goes black.

Dry — for thin-walled chiles only

Cayenne dries beautifully; a serrano gives up too much aroma. 125 °F until brittle, 8–12 hours. Above about 145 °F you cook off the volatiles you grew the plant for.

Cool completely before jarring. Store whole and grind in small batches — ground chile goes flat within months and whole pods hold for years.

Refrigerate — the short bridge

• Peppers: 1–2 weeks in a bag with a little airflow.
• Tomatoes: never. Below about 55 °F, flavour-volatile production shuts down permanently and does not restart. A refrigerated tomato is a permanently worse tomato.
• Herbs: stems in water on the counter, like flowers.

Cure the alliums

Onions and garlic are not stored, they are cured first, and skipping it is why they rot in November.

1. Pull whole, tops attached.
2. Lay out in shade with real airflow — not sun.
3. Onions: 2–3 weeks, until necks are papery and tight.
4. Garlic: 3–4 weeks, until the outer wrappers are dry and rustling.
5. Trim tops to an inch, roots to a quarter inch.
6. Store cool, dark and dry, never in a sealed bag.

Cured properly: onions hold 4–6 months, hardneck garlic about 6.

The frost call

When frost is forecast, strip everything.

• Green tomatoes ripen indoors at room temperature. Slower and slightly less sweet, but genuinely usable.
• Peppers finish colouring off the plant, especially if you leave a length of stem.
• Basil is destroyed at about 50 °F — well before frost. Take the whole plant a week ahead and turn it into pesto for the freezer.

Nothing on the plant survives the first hard freeze. Everything you pick the day before is a jar.
