Oca

22 February 2024

There are so many interesting vegetables and fruits. We’re always keen to try something new, so last year when we found mashua we simply had to try it. And how about sand carrots?
This week we spotted oca at our bio-supermarket. Small red tubers from Peru. Hopefully not imported, but we bought them anyway.
Oca (Oxalis tuberosa, known as yams in New Zealand) originates from the Andes. It is grown in the highlands of several countries (Ecuador, Peru, Chile, Argentina). Oca’s are also cultivated in various other countries, including the UK, Mexico, New Zealand and France.
Oca is a member of the family of wood sorrels and the plant has clover-like leaves. The leaves and the stems are also edible. Nutrient wise oca tubers and potatoes are very similar. The oca tubers contain a high amount of vitamin C, calcium and iron. Oca tubers can be acidic, thanks to the presence of oxalic acid. The tubers have a lovely soft, red colour. 

Oca tubers can be eaten raw, boiled and baked. We tasted a few slices of raw oca, only to find the texture not great and the taste a bit tangy, radish like. We decided to bake them in olive oil. The result was a pleasant surprise and some of the colour is still visible. The tubers tasted like a really, really good potatoes: soft and nutty.

What You Need
  • 250 grams of Oca
  • Olive Oil
  • Black Pepper
What You Do

Preheat your oven to 180 °C or 355 °F. Wash the oca’s. Don’t be tempted to peel them because the peel is very tasty. Remove small bits of dirt with a sharp knife. Wash again and dry. Add olive oil to a baking dish, add the tubers and make sure they are nicely coated. Transfer to the oven and fry for 15-25 minutes, depending on the size. Allow to cool for a few minutes before adding black pepper.

Mashua

26 January 2023

This edible, very productive plant (Tropaeolum Tuberosum ) is originally from the Andes. It grows very well in colder climates, it’s not very demanding and comes back year after year thanks to its tubers. Other names include Capucine Tubéreuse, Knollige Kapuzinerkresse en Knolcapucien.
We saw Mashua Tubers in our local bio supermarket and we bought them, without having a clue how to prepare the tubers.

The leaves are supposed to taste like Indian Cress (same family) and the deep orange-red trumpet flowers will do very well in a salad. The leaves can also be turned into pesto or prepared like spinach. The tubers (vibrant yellow with an intriguing purple pattern) are often used in stews and soups. They can be eaten raw in a salad, grated or thinly sliced. Not our favourite. The taste is radish like, but sharper and not very elegant.
The taste and the texture of the cooked mashua tubers took us by surprise: delicate cocoa but not sweet, moist and with a pleasant structure thanks to the peel.

We combined our Mashua with chicken and shiitake, a combination that worked very well, although we must admit we were a bit overwhelmed by the Mashua!

Wine Pairing

A medium bodied, fruity, non-oaked red wine will go very well with the Mashua. A glass of Merlot perhaps?

What You Need

  • For the Mashua
    • 5 Mashua Tubers
    • Cumin
    • Shallot
    • Olive Oil
  • For the Chicken
    • 2 Organic Chicken Thighs
    • 50 grams of Shiitake
    • Olive Oil
    • Black Pepper

What You Do

Wash the mashua (don’t peel them) and cook for 5 minutes. Let cool. Slice the tubers lengthwise in two. Dry with kitchen paper. Peel the shallot, quarter and slice. Warm a small skillet. Add a generous amount of olive oil to the pan, glaze the shallot for a few minutes, add cumin (crushed seeds preferred) and then add the halved mashua. Leave for 30+ minutes until just a bit soft. Turn them occasionally to coat the roots with the flavours of the oil, the shallot and the cumin. No need to colour them. Add some extra cumin 5 minutes before serving.
In parallel, fry the chicken thighs and transfer to the oven (60 °C or 140 °F). Clean and slice the shiitake, add to the pan and fry. Add the chicken, allow to integrate. Add black pepper to taste.
