Rhubarb (or Pie Plant)
Fruit or vegetable, rhubarb is making a comeback. Found in many home gardens, a rhubarb plant is the plant that keeps on giving, and giving, and giving. It’s pretty impossible to kill a rhubarb plant, not that you would ever want to! You may know it as pie plant (so named because rhubarb makes a great pie!).
Here in Michigan, it’s absolutely the first crop to be harvested in the spring, and it’s always so welcome. Just when we think winter is going to last forever, the snow melts, the ground warms up a bit, and up through the ground, pink knobs of rhubarb emerge. The stalks grow so rapidly, you can literally see the change overnight. Stretching toward the sun, long stalks with gigantic leaves beckon to be made into delicious spring time treats.
My mom always made rhubarb sauce with rhubarb fresh from her garden. It’s so easy and flavorful. Since it’s really quite sour on its own, you need to add a fair amount of sugar to make it palatable. Experiment a little until you find just the right balance of tart/sweet for you.
Rhubarb Tips
Rhubarb is a vegetable that’s more commonly used as a fruit. It’s often used to make pies, sauces, cakes, bars, and so on.
There’s no need to peel rhubarb. Even though it may look kind of stringy, it will all cook down and be perfectly tender and edible. Never eat the leaves because they contain a toxic substance.
You can eat rhubarb raw, too, but it is super tart. Add very thin slices to salads for a nice crunch and burst of flavor.
How To Make Rhubarb Sauce
Think of rhubarb sauce like applesauce or peach sauce. It’s basically cooked fruit with a little sweetener, in this case, sugar.
Prep the rhubarb. Preparing the stalks to cook is easy. Simply cut off the leaves. Don’t be tempted to eat the leaves because they contain a substance that is toxic when eaten in large quantities. Wash the stalks thoroughly, and chop with a really sharp knife into one inch pieces.
Cook it on the stove. Put the chopped rhubarb into a large saucepan, add a splash of water (not too much, rhubarb is pretty juicy on its own), and sugar. Cook over medium to low heat until the rhubarb chunks have broken down and formed a nice sauce.
Make as much as you like. You can double or triple this recipe easily since there are only a couple of ingredients. It just depends on how much rhubarb you’re lucky enough to have. You could also add some strawberries. It’s a very forgiving recipe!
How to serve rhubarb sauce
Serve rhubarb sauce at room temperature or chilled. You can easily make a big bowl of it and keep it in the fridge for a week. It’s ready to eat any time you are.
Eat a bowl of rhubarb sauce for breakfast, lunch, or dinner. Serve it as a delicious sauce for pancakes or waffles for breakfast. Stir it into plain yogurt. Top vanilla bean ice cream or pound cake with rhubarb sauce for dessert.

How To Freeze Rhubarb
If you have a lot of rhubarb, it’s very easy to freeze. Wash, dry, and cut into small pieces (about one inch). Spread on a sheet pan and freeze for about an hour until frozen. Then, move it to an airtight storage container or freezer bag and freeze for up to 6 months. This method prevents the pieces from sticking together.

Notes
- Increase yield: Recipe can be easily doubled or tripled depending on how much rhubarb you have.
- Storage: Rhubarb sauce can be refrigerated for up to one week or frozen for up to six months in a freezer safe container. Thaw overnight in the refrigerator.
- Tip: If desired, add a couple drops of red food coloring. This is particularly helpful if your rhubarb is more green than red, which can depend on what type of rhubarb you happen to have. The color doesn’t affect the flavor, so it’s more for visual appeal.
- Strawberry-rhubarb sauce: Substitute 2 cups sliced strawberries for 2 cups of the rhubarb. Cook as instructed.

This makes a most delicious dessert!!! Layering white bread in bottom of pan or individual dish, pour heavy cream over top to saturate. Layer same again and a third layer of you like! The cream sets up because of the rhubarb, and everyone loves it!!! Sprinkle a little sugar on top if it isn’t sweet. The bread softens and it becomes like a rhubarb custard dessert. Try it in a single dish for yourself!
