Potatoes are the most grown crop in the world, and although in the UK we are quite fond of the potato - chipped, mashed, on top or in a pie, from a packet or crisp-skinned and stuffed with beans. This weekend we’re off to celebrate and sample some of the amazing varieties of potatoes grown in the UK at The Garden Museum. One variety that were are particularly excited about is the oca, so excited that we put in a special order to our local grocer for an advance preview. Ocas originate from the Andean region of South America, but are also now grown by specialist growers in the UK with a limited season (January- May). They can be cooked in the same way as other potatoes but the can also be eaten raw. The idea of eating raw potato has never really appealed, but raw ocas pack a citrusy fresh crunch. To celebrate eating raw potatoes and this sudden burst of spring-like weather, we’ve developed a citrusy potato salad that marries South American and seasonal flavours. The citrus chilli dressing lightly pickles the shallots and the oca’s making this much like a fresh, plant-based ceviche. Get yourself some of the adorable little tubers while they’re available and give it a go!
