You’ll need a selection of freshly picked lettuces such as round lettuce, oak leaf lettuce, lamb’s lettuce, watercress, cos lettuce, little gem lettuce, chicory and radicchio (about 4 large handfuls). You’ll also need a jam jar dressing of your choice.

To wash your salad leaves:
When you get your lettuces home, remove the roots and any not-so-nice outside leaves first, then click or tear off the rest of the leaves and give them a good old wash in cold water. Once they’re clean, give them a spin in a salad spinner or shake them dry in a tea towel.

Add the garlic, chilli, rosemary and anchovies to a food processor and whiz until fairly fine. Dice and add the cold butter, then whiz again until well combined.

Get yourself a good-sized piece of greaseproof paper and place the butter into the centre. Fold the paper over and roll it around until you have an even-sized log. Twist up the ends to seal then pop in the fridge or freezer until needed.
