Hot and tangy celeriac remoulade

Method

1. Add the lemon juice to a large bowl. Cut the peeled celeriac into thin matchsticks using a food processor with a grater attachment (or a julienne peeler or sharp knife). As you work, put the cut celeriac pieces in the lemon juice and give them a stir to stop them turning brown.

2. Bring a large pan of water to the boil and get the bowl of iced water ready. Drain the celeriac (reserving the lemon juice), then add to the boiling water for just 15 seconds. Drain, then transfer immediately to the iced water to halt the cooking process. Leave to cool for 5 minutes, then drain again, squeezing to remove as much liquid as possible.

3. Whisk together all the remaining ingredients, including the leftover lemon juice, in a large bowl. Season with plenty of salt and pepper, then stir in the drained celeriac.
