Cook the pasta in 1% salted water.

Cut the backs off the prawns, remove the entrails and cut the avocado into large dice.
Sauté in a hot frying pan until the prawns are lightly cooked on both sides, then add the avocado and cream.

When the cream has reduced slightly and thickened slightly, add the cooked pasta and lemon juice and mix well.
Add a little salt if it is not salty enough.

Finish with lemon zest and pepper!
Only soak the yellow part of the lemon peel. The white part is bitter.
