EVERY WEEK I take £5 to Ridley Road Market in Dalston, Hackney, London E8 2LH, to spend on seasonal food, obviously not including items likely to be already in a kitchen, such as sauces, oil, herbs and spices.

On Friday I tell you what I have chosen and publish a healthy seasonal recipe.

As usual, expenditure on any extra ingredients, eg, flour, will be recouped by usage over subsequent weeks.

Some of the recipes will be frugal. They will all be vegetarian. They will be tasty. 

This week’s £5 basket (picture below)

Bowl of broccoli (3 heads) £1; bag of Suffolk Linroyale potatoes (1.5 kg) £1; sweet potatoes (3) £1.10; box of eryngii mushrooms (1kg) £1.50… total £4.60

HOW EXCITING —  a mushroom I’d not heard of, let alone cooked.  The name on the box was eryngii, which a quick surf showed was Pleurotus eryngii,  also known as the king oyster, emperor, trumpet and French horn.

Whatever name Londoners eventually settle on, foodies are likely to love its distinctive taste, and strong texture. To my non-fungus-expert eyes, it looks like a cep/boletus.

In any case, it’s a pleasing find, especially when the only English price I could find on the internet was £2.10 for 100g. In the market I paid £1.50 and got ten times that weight.

That’s enough about my find. Now for this week’s recipe.

Potato salad with cumin seeds. Serves 2

Equipment: kitchen knife, medium-size saucepan, small frying pan, teaspoon, tablespoon, salad bowl. Scrub potatoes and wash herbs.

Preparation: 10 minutes, cooking 10 minutes

Ingredients: 4 potatoes (Linroyale looked good value this week) about 400g unpeeled and cut into bite-size pieces, 1/2 an onion peeled and finely chopped, 1 teaspoon cumin seeds, fresh herbs of choice, 1 tablespoon oil, seasoning.

I do not like potato salad with mayonnaise, which I find rather cloying in the mouth. This recipe for potato salad is fresh and light to taste.

Method: Pour cold water into the saucepan until it is 3/4 full. Add a good pinch of salt and place the potato chunks into the saucepan, cover and bring to the boil. Turn the heat down and simmer for 10 minutes. Do not overcook because the potatoes need to keep their shape and have a firm texture. 

Meanwhile, dry-roast the cumin seeds in the frying pan over a gentle heat to release their oils and aroma. In a bowl add the chopped herbs, I’m using mint and chives. If you have any celery left over from another meal, finely chop it and add. 

Mix in the chopped onion and cumin seeds. Drain the potatoes and add to the bowl and stir gently to mix all ingredients. Add the oil and mix again.

I am serving my potato salad  and lightly steamed broccoli with the mushrooms gently fried in butter.

Tip: If the hot weather continues, the market traders will want to  get rid of all their fruit and veg on Saturday because a lot of the soft fruits and leafy greens will not keep in the heat of their nearby lock-ups overnight and on Sunday. And some stalls do not open on Mondays. So if stalls have a lot of perishable stock left after 3pm, prices usually will be reduced until by 4pm nearly all is gone. You may find cheaper buys than I found for my weekly Rambling Down Ridley Road basket.
