An easy elegant dessert. I used in-season strawberries rather than blueberries (plus that seemed more valentine-y). The cream is great - I thought it was going to be to sweet, but the tang of the sour cream balances nicely. It is quite firm, so I had no trouble removing it from the dish and cutting even slices. I think any fruit syrup would be nice, perhaps with some chocolate shavings. I would omit the mint - it didn't seem to add much flavor, and did sort of give the appearance of dead leaves in the syrup. The instructions could be clearer, with appropriate quantities of sugar and zest listed in each section, and the addition of the cinammon stick mentioned.
