Last year I tried growing oca on the allotment without much success. This year they are a real triumph and I am trying all sorts of recipes with them. It seems I dug them up too early last year and the tubers were only small. This year I have been more patient and it has paid off.
The oca plant produces tubers in a similar manner to potatoes, a bit similar in shape to Pink Fir Apple, albiet somewhat smaller. Being of a completely different family to potato it remains unaffected by blight and other associated pest and disease problems and are really pretty plants.
Oca or Oxalis tuberosa is a marvellous root vegetable that overwinters as underground stem tubers, it was brought into cultivation in the central and southern Andes for its tubers. Oca was introduced to Europe in 1830 as a competitor to the potato, and to New Zealand, where it is commonly grown, as early as 1860.
At the moment there are no proper named varieties although there are several distinct types, each lovingly named according to its skin colour which can be yellow, pick or cream-white.
They are delicious and so useful. So far I have roasted them, eaten them raw grated into salads, steamed them and eaten them with butter or creme fresh and the latest recipe is to use them in a vegetable pie.
So using the potato pastry from my previous blog (perhaps I’ll try making the pastry with oca next) I lightly sauted together in a frying pan with a little oil the following:
1 red pepper, 150 g sliced mushrooms, 150 g oca, part steamed and cubed, 1 leek, 1 teaspoon mixed chopped fresh thyme, rosemary and sage and 1 tablespoon chopped fresh parsley, salt and pepper. You could add dried herbs, I used the fresh as they were in the garden.When they are cooked but still have a little bite to them put them in a pie dish with 4 whole hard boiled eggs (or leave these out if you want a vegan dish). Cover with the pastry crust, brush with egg and cook for around 35 mins or until golden at 190oc/375of/gas5
