Vegan Upside Down Rhubarb Cake (Spirender Veganer) takes the conventional pineapple upside-down cake back to England and Scandinavia, where this fruit is so popular. The cake recipe is pretty straightforward, then the baked cake is served wtih vegan cream or vanilla ice-cream.
Rhubarb is too bitter to eat without sugar or being cooked. The leaves can’t be eaten. But they contain a toxin that could harm creatures. So don’t compost them, just bin them to naturally biodegrade.
