Sweetcorn now in stock

One of the most endearing scenes in the movie Big (where Tom Hanks plays a little boy magicked into a man’s body) is when he picks up an ear of baby corn and eats it, typewriter-style, at a fancy event. Of course, baby corn usually tastes of nothing but tin, but at least you don’t have the problem of what to do with the cobs afterwards.

If you’re getting through a heap of sweetcorn this summier, let me introduce you to an excellent kitchen hack: you can turn those nibbled cobs into the sweetest, most flavoursome stock ever. It doesn’t make them fit into your worm farm any easier, but at least you’re extracting maximum value first.

SWEETCORN STOCK

Gather as many cobs as you have – ideally 4-6 – and put them in a large pot with half an onion, a well-washed carrot and a stick of celery. Cover with cold water. Cover the pot and set over medium heat. Let it come to the boil, then simmer gently for 40 minutes. Cool and strain into suitable containers with lids. Refrigerate and use within five days, or freeze for up to three months. And if you’re wondering what to do with sweetcorn stock, the following recipe should do the trick nicely.

SWEETCORN AND KUMARA CHOWDER

Save this for a rainy day (there’s bound to be one along soon!)

2 tablespoons butter
1 onion, finely diced
½ teaspoon flaky sea salt
½ teaspoon turmeric
1 tablespoon chipotle in adobo sauce (roughly 1 chipotle, with a bit of sauce around it)
3 ears sweetcorn, kernels shaved
1 medium kumara, peeled, diced
2½ cups sweetcorn or other vegetable stock
⅓ cup creme fraiche, plus a little more for garnishing if desired

Melt the butter in a large saucepan set over medium heat. Add the onion and cook for 5 minutes, stirring occasionally, until it is beginning to soften. Add the salt, turmeric and chipotle. Add the corn kernels and kumara. Stir well, then add the stock. Bring to a gentle simmer, then cover and cook for 10-15 minutes, until the kumara is soft.

Remove from the heat and puree, either using a stick blender, a food mill or a food processor. Return to the saucepan and taste for seasoning – add more salt if needed. If the soup seems very thick, add a little boiling water. Stir through the creme fraiche and reheat gently. Serve hot, garnished with a little extra creme fraiche and a drizzle of chipotle sauce.
