Spicy rhubarb and sweet, buttery crumble topping are a match made in heaven.

Enjoyed for generations, this old-fashioned rhubarb crumble recipe is — in a word — divine.
The tartness of the rhubarb is combined here with the sweet crumble topping and a hint of orange zest to create an easy, dreamy dessert.

The recipe for rhubarb crumble
There are different recipes, but this one is from a book I found in Nana Ling’s collection.
In 1948, the Australian Women’s Weekly published a ‘cookbook’ containing award-winning recipes from their ‘cooking competition’.
As you can imagine there are so many wonderful recipes in the pages of this book including this one for Hot Rhubarb Crisp.

Although there seems to have been some difference between chips and crumbles in the past, most foodies today agree that “the lines have been blurred over the years and what used to be called chips is called crumble and crumble is now called chips”. .
I chose to call this recipe Rhubarb Crumble as I think it’s probably the most commonly understood term these days, at least in Australia.
