I wasn't sure what to do with this unusual vegetable, so I cooked a few Oca tubers
until they were soft. Just a little salt in the water.
Mashed them up with a little milk. I think I prefer the taste like this. Hard to describe but the Oca mash
tastes a little bit like pease pudding, or perhaps mashed swede or chic peas. Would be quite nice as a veggie with a roast dinner. I might try adding butter and pepper next to see if it improves.
