Oh my god these are amazing. We ate them all in about 2 days flat.
OM NOM NOM. They held together fantabulously.
I happened across the recipe at Heathen Vegan. Oh yum.
I accidentally made twice the amount of custard (I measured up a pint of each milk rather than 1/2!) so I got a couple of extra tarts, and ate a crap load of custard. Mmm. I'll be making these again and again.
