No-cook citrus cheesecake with lime drizzle

Ideally a pudding should suit all the guests, but my recipes for no-cook cheesecakes have always included gelatine. This makes the pud unsuitable for vegetarians, so in search of a no-cook, no-gelatine recipe the other Lucy and I have made, tasted and eaten too much of too many! Don’t miss out the drizzle here as it really makes this cheesecake.
