Most of my recipes for rhubarb are for sweet things so I'm afraid I'm not much use to you. But I thought I'd mention my favorites here in case anyone else has a rhubarb mother-load.
Rhubarb cornmeal cake by Nigella Lawson - wonderful, not overly sweet cake. The muscat mascarpone sauce that accompanies it makes it really special.
Rhubarb and ginger bars from Guardian Cook supplement - these were gorgeous, a pink rhubarb curd on a crust base. That edition of Guardian Cook has a lot of great looking rhubarb recipes, many of them savory.
And of course the classic rhubarb crumble is always popular.
Don't forget about the huge repertoire of online recipes we have on EYB - there are 1,179 recipes using rhubarb of which 388 recipes are not desserts or baking. I want to try the Beetroot and rhubarb salad by Yotam Ottolenghi.
