Rabarbersaft

The rhubarb appears before anything else. Late April in Denmark, when the soil is still cold and the garden looks like it hasn't decided whether to wake up, the rhubarb pushes through. Fat red stalks with crumpled leaves, unstoppable, the first real sign that the kitchen is about to change seasons. And the first thing you do with it, before the cakes and the compotes and the tarts, is make saft.

Rabarbersaft is the cordial that fills Danish refrigerators from May onward. Every household has a version. Some add vanilla. Some add ginger or elderflower. The one I'm giving you is the clean, classic recipe: rhubarb, sugar, lemon, water, and time. It's the version that lets the rhubarb speak for itself, tart and floral and so pink it stops you when you hold the glass up to the light.

The technique is gentle. You simmer, you don't boil. You steep, you don't rush. And when you strain, you let gravity work without your help. That patience is the whole secret. The result is a concentrate you keep in the fridge all summer, pouring a few centimetres into a glass over ice and topping it with cold water whenever someone walks through the door. This is how we greet each other when the days get long. You'll make it once and then you'll make it every spring.
