What goes well with Rhubarb? Ginger of course! Not tried it, well let me tempt you with this Rhubarb & Ginger Crumble Cake. I can’t help but smile when I see rhubarb on the shelves in the shops, you’ll probably start to see the unmistakable pink stalks in store soon if you haven’t already? I’m one of the lucky ones who has their own personal supplier in the form of my father-in-law who picks me some from his allotment every year. Rhubarb doesn’t mind being frozen so I always cut it into inch lengths and bag portions up for freezing, that way I can have rhubarb all year round.

I had no idea rhubarb was so good for you until I did a bit of research; did you know that the stalks contain impressive levels of several B vitamins, vitamin C, vitamin K, antioxidants and minerals. I knew the leaves were toxic but never understood why; basically the leaves hold high levels of Oxalic Acid, which is highly toxic to humans. Also we’d not have the rhubarb plant here in the UK had it not been for Marco Polo who brought the plant to Europe, and it finally set root in America thanks to Ben Franklin! And guess what? It’s not even a fruit, it’s a vegetable, which kind of makes sense given the seed rule but still, I don’t fancy it with my Sunday Roast!

This bake has been topped with a divine ginger crumble mix that uses Delicious Alchemy’s Oaty Cookie Mix I had one packet left and knew ages ago this was what I wanted to bake with it. I’ve made this before using plain flour, caster sugar, butter and ginger but guessed…and was right…that this cookie mix would add a far better crunchy topping. Other bakes made with this mix are my Raw Chocolate Truffle (cake pops) and my Bailey’s Baked Cheesecake

Check on your bake after 45-50mins you may need to cover with foil for this last part of the bake to prevent the crumble from colouring too much.
