Dandelion

Everyone has pulled a dandelion; almost nobody has cooked one properly. The leaf is bitter, and the whole technique is about managing that bitterness rather than pretending it is not there. The root is a different proposition entirely — roasted and ground, it is the closest thing in a European hedgerow to a coffee substitute that is actually worth drinking.

Bitterness is a schedule, not a fixed property

The same plant is mild in April and ferociously bitter in July. Bitterness tracks the plant’s age and the temperature: young leaves in cool weather are sweet enough to eat raw in a salad, and the sesquiterpene lactones that make it bitter — taraxacin among them — rise steadily once the plant is under heat stress and in flower.

The practical consequence is that you pick in the two narrow windows and you pick small. In April, take only leaves from the centre of the crown that are under 12 cm. In September, after the summer heat has broken, the plant flushes again and those leaves are almost as mild. In between, the leaf is only worth having if you are going to blanch it hard and use it as a bitter element, in the way you would use radicchio.

The blanching method that actually works: 90 seconds in heavily salted water, then a second 60 seconds in fresh water, tasting between the two. The bitterness drops by roughly half each time. Two rounds is enough for a soup; three makes it a vegetable in its own right.

The forcing trick, which is better than picking

The best dandelion greens are not gathered at all — they are grown. Dig a crown in late October with 15 cm of taproot and pot it in damp sand in a dark cellar. It will push pale, elongated leaves in three to four weeks that have a fraction of the bitterness of a field leaf and a texture closer to a butterhead lettuce.

This is the same principle as Belgian endive and it works identically on dandelion. One crown gives two or three cuttings through the winter, and it is the only way to get a genuinely sweet dandelion leaf without waiting for April.

If you do not have a cellar, a bucket with a lid in a cool shed works. The temperature should be 8–12 °C; warmer than that and the leaves go leggy and bitter anyway, colder and the crown does not break dormancy.

Root: the coffee that deserves the name

Lift roots in late October once the leaves have died down, scrub rather than peel, and slice at 3 mm. Roast at 180 °C for 25–35 minutes, turning once, until the slices are a deep mahogany and smell of dark chocolate and toast. Under-roasted root tastes of soil and over-roasted root tastes of ash; the window between the two is narrow, so watch the last ten minutes.

Brew 12 g of roasted, ground root per 250 mL, simmered 8 minutes rather than steeped. The result is bitter, sweet and full-bodied, with no caffeine. Blended 50 : 50 with roasted chicory it makes a very close approximation of a dark coffee; on its own it is a good drink in its own right.

The same roasted root goes into a dandelion and burdock syrup, which is the traditional British soft drink: 60 g of roasted root, 30 g of roasted burdock root, 1 L of water, simmered 30 minutes, then 400 g of sugar and 30 mL of black treacle stirred in and reduced to a syrup. Dilute 1 : 5 with soda.
