Candy, tart, and jammy, strawberry rhubarb pie is the quintessential spring dessert. Come spring and early summer season, I scour the farmers’ marketplace for these brilliant crimson rhubarb stalks, able to load the trunk of my automobile with as a lot as I can match. Rhubarb season is fleeting—and the one acceptable transfer is to take full benefit of the second by shopping for kilos and kilos of it to show it into crisps, pickles, compotes, and, after all, pie.

In principle, making a strawberry rhubarb pie is straightforward. You chop up your fruit (although I ought to level out that rhubarb is technically a vegetable), toss it with sugar and your thickener of alternative, encase it in pie dough, and bake till effervescent and golden brown.

The one drawback?

In my try and nail down the proper strawberry rhubarb pie, I baked a dozen, and did additional experiments that zeroed in on among the filling variables till I got here up with my splendid model.

The Proper Ratio of Fruit and Dicing Choices

As a result of I needed a flavorful pie that allowed each the strawberries and rhubarb to shine, I began with a 1:1 ratio by weight of strawberries to rhubarb, each finely diced. What I didn’t understand was simply how a lot water the strawberries would contribute to the pie filling. Even with an ample quantity of thickener, the pies made with equal elements strawberries and rhubarb had been invariably too free. You would possibly marvel, why not simply use extra thickener? We may, however merely growing starch till the liquid is thick sufficient solves one drawback whereas creating one other: Stabilizing extra liquid with much more starch ends in a stretchy, slimy filling that—whereas actually thicker—isn’t interesting.

With this in thoughts, I adjusted the ratios to cut back water from the strawberries, choosing two elements rhubarb to at least one half strawberries. As an alternative of a advantageous cube—which I believe uncovered slightly an excessive amount of floor space that allowed extra water to leach out and created a runny filling—I opted for 1/2-inch items. This was the best dimension of fruit: massive sufficient for the items to stay distinct, however sufficiently small to melt and cook dinner down right into a barely jammy filling.

Whereas this mounted the feel drawback, it threw off the flavour stability. I needed the pie to style distinctly like a mixture of strawberries and rhubarb, however now it was too rhubarb-forward. To make up for the lower in contemporary strawberries, I folded in a number of tablespoons of strawberry jam, which helped intensify the berry taste with out contributing any further water.

Stopping a Runny Filling: What Type and How A lot Thickener Ought to You Use?

Have a look at most fruit pie recipes, and also you’ll see that they sometimes name for all-purpose flour, cornstarch, potato starch, or tapioca starch as a thickener. It’s because most fruit utilized in pie fillings (assume berries, stone fruit, or apples) maintain loads of water that’s launched through the cooking course of. With out a thickener, you’d find yourself with a runny pie—however there’s solely a lot a thickening agent can do that can assist you obtain a just-set filling that’s neither soup nor sludge.

The very best pies—which have a brilliant freshness and a jammy texture—rely on correct moisture administration, which may be achieved a number of methods. My testing already addressed the ratio of strawberries to rhubarb and the way massive to cube them, however I used to be concurrently tinkering with different variables to zero in on my splendid taste and texture. A type of variables: the sort and amount of thickener. As I wrote above, extra thickener doesn’t clear up all issues. With a purpose to get my filling to work, I needed to not solely swap up the ratio of fruit but in addition experiment with totally different thickeners and strategies of incorporating them.

I began utilizing tapioca starch, former Critical Eats editor Stella Parks’ most popular pie thickener, which units fruit fillings with out turning into overly gloppy. I used 5.5% of the entire weight of fruit, Stella’s beneficial quantity of starch. However even after decreasing the quantity of contemporary strawberries in my filling, it nonetheless wasn’t sufficient to soak up the quantity of liquid they unleashed. After I elevated the quantity of starch to six%, the filling managed to by some means be each too free and too gelatinous, underscoring the purpose that merely including extra thickener wasn’t going to be the only resolution to the issue.

The Foolproof Method for Thickening Strawberry Rhubarb Pie

After I first revealed this recipe in 2023, I known as for minute, or quick-cooking, tapioca pearl fragments. Finely floor minute tapioca resulted in a pie filling that was simply set and jammy sufficient to barely ooze out of the pie when minimize into. A number of readers, nevertheless, talked about that the tapioca by no means absolutely dissolved of their pie and resulted in jelly-like blobs. With this in thoughts, I went again to the kitchen and commenced experimenting once more.

I finally landed on a a lot less complicated technique: I macerate the strawberries and rhubarb to attract out extra liquid and focus the strawberry and rhubarb’s flavors, then briefly cook dinner it on the range. I toss the fruit in cornstarch and pectin, reincorporate a number of tablespoons of the macerating liquid to hydrate the starches, then deliver it to a simmer to assist it gelatinize. The pectin is essential right here as a result of strawberries and rhubarb each have low portions of pectin, a naturally occurring polysaccharide and fiber that helps set pies and fillings, the addition of a number of tablespoons helps encourage the filling right here to set.

It is a related technique to how some savory pies, together with hen pot pie and shepherd’s pie, are made. You sauté the aromatics and meat, coat it in a number of tablespoons of flour, after which deglaze with a liquid like water or broth. Finally, this model is far less complicated and extra simple—and it ends in a just-set pie with no jelly-like blobs in sight.
