Serve Strawberry Rhubarb Crumble with Vanilla Ice Cream - Blue Willow Dessert Bowls

Every May I begin looking for fresh rhubarb in the grocery stores. My mom used to grow it in her garden, and I miss having the fresh vegetable to make rhubarb pies. So yummy.

So far, I haven’t seen rhubarb in the stores yet, but I am hoping it will be available soon. Fortunately, I happened to freeze some of the fresh rhubarb from last year’s supply and used it in this recipe.

To Freeze Fresh Rhubarb

It’s simple to freeze fresh rhubarb. Simply wash and trim the stalks (much like you would for celery).

Cutting the Rhubarb

Then slice into 1 1/2″ pieces. Place the slices in a quart freezer bag and remove as much air from the bag as possible. You may store rhubarb in the freezer for up to 6 months, although I have kept mine for as long as year.

Note: You’ll notice I’ve added an apple to this recipe. I was running a bit short on my ingredients and decided to slice an apple to include with it. While you do not need to do so, I thought it really added to the flavor of the filling. Rhubarb goes really well with strawberries and apples.
