The pastry crust didn't turn out to be as flaky as I would hope for, but I like that it's very light. The lemon filling is, as suggested, sublime. I just bought the creme brulee torch on Friday but I haven't got the time to buy the butane gas (by the way, why can't those places which sell the torch don't have the gas?), so I just sprinkled some icing sugar on top. It could do without.
Ever since I started baking (we're not talking about a long time, I started baking last month!), I have gained 5 lbs. This tart can't stay home any longer so Francis and I each ate a tiny slice, and I'll bring the tart to office tomorrow.
