Oca is a very tasty and useful vegetable tuber. It grows well for me in North Wales. It’s good ground cover and polycrops well with taller partners such as tomatoes. Fresh picked and raw, many varieties have a lemony (oxalic acid) taste which goes after exposure to the sun. The cooked taste is sweet. The texture ranges from that of a slightly less crunchy water chestnut to a soft puree which depends on the variety and how much you’ve cooked them.
Cooked they can be steamed, boiled, roasted, fried or sauteed. They can be used in sweet or savoury dishes and preserved or frozen.
When we first started to grow them in 2011, I tried to find traditional recipes for them, without much success. Lost Crops of the Incas says that: “In Mexico, oca is commonly sprinkled with salt, lemon, and hot pepper, and eaten raw.” The other recipes for them I could find were for roasted oca, or oca used in meat stews.
So I thought I’d have a go at producing a set of new recipes for oca in its new home. I’ve already written about Oca Homity Pie and Warm Oca Salad.
Here I give you oca used as a pizza topping. I think this is a first on the internet, although I’m very happy to be proved wrong.
This is delicious! The oca are sweet and they have a little bite still. I think the oca look like jewels: the colour variation with fresh coriander garnish certainly makes a visually striking pizza.
This makes one pizza of about 23cm (9 inches) circumference.
Pizza is best cooked in an oven as hot as you can get it, with the oven shelf in the top half. So preheat your oven to at least 230°C, higher if you can. I cook my pizzas on baking paper on a granite baking stone. If you’re not lucky enough to have a baking stone or a pizza stone, make the pizza up on oiled
