Rhubarb and Gin Crumble

Rhubarb and Gin Crumble


This is my rhubarb and gin custard slice with wattleseed and walnut crumble. This dessert is inspired by my rhubarb gimlet that I created for world gin day today. This is an absolutely delicious desert that brings together the beautiful native ingredients from Archie Road signature dry gin to infuse the fresh rhubarb as well as some old-fashion 

aromatic bitters to bring a wonderful spicy flavour to the rhubarb and the shortbread base.

The vanilla bean creme patisserie middle layer brings a lovely sweet gooey centre to this slice which is balanced really well with the sour rhubarb. 


What is not to love?  Shortbread, custard, rhubarb and gin!
