Help me make a rhubarb tart!!

[kirstygem]

Have been given a sack full of rhubarb from a friend at work and need to use it up. Would like to make a tart to take to a buffet lunch where it be served cold.
I would prefer not to have to make pastry from scratch so the easiest recipe possible please

Chop rhubarb into 1" chunks. Cook gently in a saucepan with some sugar until soft. For a tart, drain off excess liquid, for a crumble, leave it. At this point you can freeze it for use later.
Roll out a pack of shortcrust pastry, use to line a pie dish. Bake blind until golden. Put in the rhubarb, and roll another peice of pastry to go over the top. Decorate if you like. Sprinkle with sugar if you like. Bake until the top is golden brown.

You can also make a lovely fool - blitz the cooked rhubarb and liquid (add some elderflower cordial if you have) and mix with double cream/thick yog (or a mixof the 2).

I know this is probably a daft question but how do I bake blind??

Once you have done all that (baked blind - you can also line with crumpled foil instead of rice/beans, anything to keep the pastry from puffing up) you can 'paint' the bottom pastry layer with a wash of eggwhite, then bake that for a few minutes. It gives a leakproof glossy layer under the rhubarb. Use the rest to wash over the pastry top.
