This tart is a reminder of all things spring: fresh asparagus, mint leaves, lemon and peas. All of these perennial favorites come together in a delicious starter that’s perfect for the time when asparagus is at its best.
To shave asparagus, dig the peeler into the base end (rather than the tip) of a stalk of asparagus, and run it from end to end, keeping even pressure on the stalk. You should be able to get four to six shavings per stalk, depending on the thickness.
The puff pastry pieces can be baked ahead so that the tarts can be assembled quickly at the last minute.
