Overnight Rhubarb Sauce - close up

Thanks going out to my bestie Shawnee Sax and her sister Tanis Moore for sharing this Overnight Rhubarb Sauce. This is an old New Brunswicker’s trick from extracting the maximal flavour from rhubarb by letting it marinate in sugar overnight which pulls the juices from the rhubarb and eliminates the need to add water. The result is an intensely rhubarby-y rhubarb sauce and maintenance of the bright colours.

      Hi Aga – It is great on vanilla ice cream or on plain or vanilla Greek yogurt. You can use 1 cup of the rhubarb sauce and add 4 cups of sliced strawberries and a crisp topping to make it into strawberry rhubarb crisp. Tomorrow, I’ll post a savoury roast pork tenderloin dish with this sauce on the side. Thanks so much for asking! cheers, Karen
