Rhubarb Sauce from FIFTH GEN GARDENS

This recipe for Rhubarb Sauce from Fifth Gen Gardens captures the essence of our always long-awaited spring in Alberta. I once did a radio column for the CBC on Alberta’s Signature Foods and was completely delighted by how many listeners thought rhubarb should have made the list. People yearn for it.

I think it’s rhubarb’s sheer Prairie hardiness that has endeared it. It’s as tough as the province’s pioneer homesteaders. And, this recipe comes from someone whose family were pioneers.

Kristen Graves is one of Alberta’s youngest and mightiest Food Artisans of Alberta. She is the fifth generation to farm on the Graves family’s land near Wetaskiwin so she calls her Community Supported Agriculture (CSA) operation, Fifth Gen Gardens.

In just a few short years, Kristen has quadrupled her operation and now grows food for 85 families (COVID actually gave her a 25 family boost!). Each week Fifth Gen subscribers not only get the freshest produce imaginable, they also get a recipe card with one of Kristen’s Grandmother’s recipes on it. Kristen took time after a few long hard days of planting to send me this recipe and photos. She’s truly amazing. I hope you enjoy it. Read on for the recipe.

    Karen. I have to share my tip I learned from Helen Johnston’s mother in NB. She cut up the rhubarb in the pot she was going to cook it in, then poured the sugar over it and let it sit out all night. She would simmer it the next day and it kind of candied over night. Try it. Delish. SS
