Roasted strawberry and rhubarb butter
/Rhubarb season is here! Turn this tart veg into a thick, spreadable butter to use all day, every day.
If you’ve searched Instagram recently, it’ll come as no surprise that rhubarb is a very photogenic vegetable. The variations in color lend themselves to ombre-ing and chevron-ing to your heart’s content. But today, we’re keeping it simple by doing neither of those things.
Instead, we’re turning strawberries (fresh or frozen!) and those giant rhubarb stalks you find in the grocery store (or your garden if you’re lucky enough to grow your own) into a butter akin to apple or pumpkin. Because why should fall fruits and vegetables have all the fun?
In early spring, I use frozen berries because it annoys me that strawberry and rhubarb are a perfect combination, but their growing seasons only overlap for a hot minute here in New England. Buuuuut, I found some giant berries in the grocery store recently, so I went for it with the fresh ones a little earlier this year.
A couple of notes:
Let the berries and rhubarb cook until the juices start to get a little syrupy. You can test this by sticking a spoon into the hot liquid (DON’T USE YOUR FINGER!!!). If the strawberry juice coats the back of the spoon and doesn’t drip off entirely, you’re about done. Make sure that your berries don’t burn because they can taste bitter.
This is a TART butter because, well, rhubarb is tart and that’s the beauty of it. If you like things a little sweeter, you can add a bit of sugar or use more berries than rhubarb. OR, you can combine the tart butter with sweeter things like cakes, cookies, sweetened yogurt, and whipped cream.
Roasted strawberry rhubarb butter
Time: About 1 hour, 45 minutes, about 5 minutes active time
Yield: 12 oz (1½-2 cups)
4 heaping cups strawberries (fresh or frozen)
2 heaping cups chopped fresh rhubarb (about 3 extra extra-large stalks or 6-8 smaller stalks, chopped into 1-inch chunks)
Preheat the oven to 350.
Wash and chop the rhubarb. Combine with the frozen strawberries on a parchment-lined, rimmed baking tray.
Cook for 25-30 minutes, until the fruit is soft, the strawberries have released their juices, and the juice has started to become syrupy (see note above). Watch the berries closely after about 20 minutes to ensure that they don’t burn.
Let the fruit cool completely, about 15 minutes.
Scoop the fruit into your blender. Whatever juice gets onto the spoon is fine, but don’t add any remaining syrup.
Blend until smooth.
Store in the fridge for up to 7 days.
