These individual Meyer lemon tartlets contain four layers of lemon flavour, from the lemon thyme crust to the lemon meringue kiss. The crust and lemon curd can be made a day ahead.
If Meyer lemons are unavailable, use grated lemon peel in the tart crust and the blackberry mixture. Use 625 mL lemon juice and 300 mL orange juice in the lemon curd.
