Vegetables Tubers & Starchy 🇬🇧 CoFID 2021 · 13-620
✦ Carbohydrate energy ✦ Vitamin C ✦ Potassium ✦ Vitamin B6

Old (main-crop) potatoes are floury starchy tubers that supply carbohydrate energy, vitamin C, potassium, vitamin B6, and some fibre, with most of the fibre in the skin. They are a versatile staple in British cooking.

🍳
Preparation note

Baking is good for keeping vitamin C; eating only the flesh leaves much of the fibre behind in the skin.
