Thanks GEMRM,
My mayo lasts a couple of weeks in the fridge.
As for buying tofu. Regular, fresh tofu can last a pretty long time if kept unopened in the fridge. I don't know exactly how long, possibly a couple of weeks. There is an expiration date on the package, just like on milk. (I'd go look in the fridge, but I just ran out of tofu.) Silken tofu that is packaged in shelf-safe cartons probably has a longer shelf life.
I'll send over some more recipes this week.
