Peas
Also called green peas
Peas are sweet legumes that brighten dishes with color and flavor.
Green peas are the young seeds of the pea plant, a legume first grown in the Middle East thousands of years ago. They taste sweet, fresh and grassy with a soft, earthy finish, and they pop pleasantly between your teeth.
Cooks love peas because they bring colour and sweetness to almost anything in a couple of minutes. Stir them into risotto, pasta and curries, blitz them into a minty soup, or crush them with butter as a side.
Flavor profile
Aroma: sweet, grassy
Good to know
Origin: Middle East
Forms: fresh, frozen, canned
Season: Fresh peas are a late spring and early summer treat; frozen peas are excellent and available year-round.
Nutrition: Peas are a legume, so they bring some plant protein and fibre along with their sweetness.
Storage: Fresh peas in the pod should go straight into the fridge and be eaten within 1–2 days, because their sugar turns to starch quickly. Shelled fresh peas can be blanched for 1–2 minutes, chilled and frozen for up to 12 months. Frozen peas keep for about a year in the freezer; ice crystals or a dull colour mean freezer burn, which affects flavour but is not unsafe. Cooked peas keep in the fridge for 3–4 days.
How to use peas
Sweet Pea Maintenance
Blanching stops enzymes, preserving sweetness and color.
Creamy Purees
Starch in peas gelatinizes when tender, forming smooth purees.
The science of peas
- Like sweet corn, peas start converting their sugar to starch soon after picking. Frozen peas are usually blanched and frozen within hours, locking in sweetness, which is why they often taste better than shop-bought fresh peas.
- Blanching briefly deactivates enzymes that would otherwise dull the flavour and colour during storage, and drives air out of the tissue so the green chlorophyll looks brighter.
- Long cooking or acid turns chlorophyll into olive-coloured pheophytin, so peas go grey-green if simmered in a sauce for ages. Add them at the end for a vivid colour.
- Older, larger peas contain more starch. When cooked until tender, that starch gelatinises, which is why peas blend into a thick, creamy purée or mushy peas with no cream needed.
How to choose peas
For fresh peas, choose firm, glossy, bright green pods that feel full and squeak when rubbed together; avoid yellowing or dry, papery pods. Small peas are sweetest. Frozen peas labelled petits pois are smaller and more tender.

Peas: questions
Are frozen peas as good as fresh?
Often better. Frozen peas are processed within hours of picking, before their sugars turn to starch, while fresh peas in shops may be days old. Truly fresh-picked peas are the only exception.
How long do you cook frozen peas?
About 2–3 minutes in boiling water, or a few minutes in a pan with butter. They only need heating through; overcooking makes them mushy and grey.
Do you need to thaw frozen peas before cooking?
No. Add them straight from the freezer to boiling water, soups, sauces or fried rice. For salads, rinse them under warm water or pour boiling water over them.
Are peas a vegetable or a legume?
Botanically, peas are legumes, like beans and lentils. In the kitchen, green peas are cooked and served like a vegetable.
Why do my peas turn grey?
Long cooking and acidic sauces break down chlorophyll into a dull olive pigment. Add peas in the last few minutes, and serve them soon after cooking.

Yes. Very fresh, young garden peas are sweet and crunchy raw. Frozen peas are blanched first, so they are safe to eat thawed in salads.
