Asparagus season starts in May and lasts for around six to seven weeks. Pick asparagus when the spears reach 15cm high. Make a cut at 5cm underground with a short, sharp knife to avoid slashing any spears about to emerge. Asparagus is best eaten as soon as possible after its picked. Spears should be pared of their woody ends and cooked in a large pan of boiling water. The discarded ends can be thrown into the pot to add flavour to the water, which can be used in place of stock for a spring soup of asparagus and leeks.
This recipe for asparagus soufflé tart is a showstopper but don’t be put off by the name soufflé. This is a straightforward tart in which two egg whites are whisked until stiff then mixed gently into the custard before baking. The stiff whites hold the custard up inside the shell so it’s less likely to run over and make the bottom of your pastry soggy. Serve a starter at a dinner party to impress friends or make for yourself as a decadent mid-week dinner.
