Tomatillo

Tart green husk tomato — the base of salsa verde, and not an unripe tomato.

What is Tomatillo?

Tomatillos are a distinct species from tomatoes, wrapped in a papery husk and used green. They are tart rather than sweet, and they are not unripe tomatoes.

They are low in calories with decent vitamin C and vitamin K, and contain withanolides, compounds being studied for antimicrobial activity.

The sticky residue under the husk is normal — rinse it off before cooking.

Conditions Tomatillo may help

Based on the nutrients and fibre this food supplies. These are supporting foods, not treatments.

Best preparation & usage

Rinse off the sticky coating under the husk before use.

Roast or boil for salsa verde. Roasting deepens the flavour; boiling keeps it sharper and greener.

Firm and filling the husk is what ripe looks like.

They freeze whole after husking and rinsing.

Why Tomatillo works

Tomatillos are acidic enough to work as the souring agent in a dish, which is why salsa verde needs no added lime. That acidity also makes them useful alongside iron-rich food, as the vitamin C aids absorption.

Nutritionally they are a light vegetable — the value is in what they let you cook rather than in any single compound.

Who should avoid or limit

Kidney disease: potassium may need limiting. Ask your doctor for your numbers.

IBS: several vegetables are high-FODMAP and commonly trigger symptoms — tolerance is personal.
