Butter Bean, Leek & Sweet Potato Stew questions
Can I use a plant milk?
Unsweetened oat milk works with the cornflour in the same way and makes the stew dairy-free. Use an unsweetened one so the sauce doesn't taste sweet.
What can I use instead of sweet potato?
Butternut squash or ordinary potato works in the same weight. Ordinary potato may need a few minutes longer to soften.
Why mix the cornflour into the milk first?
Stirring cornflour into cold milk before it goes in stops it forming lumps, and a short simmer is all it needs to thicken the sauce.
