Creme Fraiche and Cheesecake

[lorcas_novena]

Hey guys,

I'm not normally big on using substitutes but really want to make a good lettuce and pea soup. Is there anything I could use as a creme fraiche substitute to hold the soup together a bit? Particularly something available in the UK.

Also, does anyone know how to make a good cheesecake without using tofu?

Thanks x
