Lemon Meringue Pie

Retro dessert, I haven't made these for about 15 years so thought it might be nice. The problem with these is that whenever it gets made they go soggy in the fridge after a day. So I blind baked the tartcases first, then the lemon filling separate and then for the meringue I did an Italian meringue and will put it in the fridge like this. Then to order I put it through the oven for about 3 minutes so the meringue goes crispy and brown on top. I serve it with a blackcurrant compote.
