rhubarb macerating in sugar

what remains.

What prep leaves on the board, and where it goes next.

Prep leaves rhubarb trimmings, onion skins, the water the pulses cooked in, the whey from a yogurt. Most of it goes into another preparation, and this page follows it there, plate by plate. Some of it still has no use here.

one box of rhubarb.

The stalks go in whole. The notebook keeps count of what comes off.

rhubarb

Stalks only. The leaves are poisonous and never come in. One page weighs a batch: 800 g in, 587 g once trimmed.

rhubarb shrub

Vinegar goes in. Rhubarb, sugar, vinegar. Sharp, sweet, and it keeps. At the bar it goes into sparkling water as the seasonal soda.

the bucket

What the board leaves through the day goes into one bucket. It boils into stock, and the stock boils down again, further down this page.

Each card is one route. The big frame is the plate it reached; the small ones are how it got there.

onion skins, into an ash oil

The dry outer layers go on a tray, into the oven until black, then ground and stirred into oil. It went over the charred onions.

onion skins, into a broth

Five grams of burnt skin in the pot with the kukicha tea, poured over the acorn crepe and mushrooms. Another recipe that season ground the burnt peel with nigella seed into a powder.

onion treacle

The onions for the spring menu roast for three hours, low and slow. What runs off them is cooked down until it falls off a spoon like this, and goes on the polenta as the house treacle.

Trimmed from the leeks in the first dish, burnt in the oven, blended with smoked paprika and carried in oil onto the mushroom. Smoke around the 'scallop'.

persimmon, frozen whole

A ripe persimmon has a short window. Frozen whole it keeps, and shaved frozen over the macadamia ricotta it does something a fresh one cannot: the ice dissolves against the cream.

the bucket, into a marmite

Everything the board leaves boils into stock. Then the stock keeps boiling: about ten litres come down to a hundred millilitres of house marmite, dark and salty, and it tastes a little different every batch.

tomatoes, water and pulp

Coração de boi tomatoes are blended whole and hung in cloth. The clear water is the base of the plate; the pulp left behind is cooked into the red currant and tomato chutney on the same plate. Two summers ago the skins were dried into a tomato salt.

cooking water, into a meringue

The water the chickpeas cooked in is kept. Whipped with sugar and cream of tartar and baked low, it was the meringue on the 'alt-choc' cake. In autumn 2024 the same water was a foam on the mushroom dish. The chícharo for the falafel cooks the same way.

Red wine, hibiscus, juniper, garlic and sugar cook the cabbage. After that the marinade is not thrown out; it is cooked down into the sauce under the same cabbage.

The stems and tops that never made the menu are salted and fermented. This summer the kimchi is churned into an ice cream, cold and sharply acidic, over the fried rice.

beetroot, salted for a week

Beetroot at its sweetest, sliced and aged a week in sea salt, which draws the water out and leaves it chewy and mineral. Blackberries from H2Douro are cooked down into the sauce that pulls the salt back into fruit.

elderflower, two weeks a year

The flowers come from Corotos for two or three weeks in late spring and are steeped whole into a syrup. The baked donut is split open and bathed in it, and it lasts on the shelf long after the flowers have gone.

ginger, and the peel from the juicer

Ginger is peeled with a spoon, so the skin comes off and almost nothing else. A ginger bug fed with sugar starts the ginger drink on the card, and the fermented ginger syrup that cut through the onion dish in spring. Beside it, orange peel from the juicer ferments with pine needles into the seasonal soda.

coffee grounds, into a clay

Spent grounds from the morning, mixed with carob, a little liquid and oil into a clay. Roots and onions slow-bake inside it. A notebook recipe bakes the same grounds with muscovado into a crust.

Not everything on this page ends somewhere. Nettles are blanched and blended into oil and then strained, and the notebook says to keep the pulp without saying what for. The rhubarb that comes out of the shrub jar is still sweet and still sharp, and it goes nowhere. The beetroot trim from the salting, the solids left in the cloth after a broth or an infusion, the grounds we do not turn into clay: all of it is the same question, which is whether there is a use we have not found yet, or whether this is simply where the line falls.

A page like this is easy to finish tidily. The kitchen does not finish tidily. What we can say is that the list gets shorter each season, and that almost everything above started here first, sitting in a container with no name on it, until someone worked out where it should go.

Endless Food CoTHIC, This Isn't Chocolate

THIC is an upcycled chocolate alternative made from by-products of the large scale food industry: gluten-free oat okara from oat milk production, and cacao husk from existing chocolate production. It's clean label, completely free from additives. Made in Denmark, THIC acts just like conventional chocolate, but with up to 84% lower greenhouse gas emissions than traditional dark chocolate.

Here it goes into the ganache on the alt-'choc' tarte, the mole on the fried wild leaves and, in spring, the sauce under the onion that roasts for three hours.
