(on perfect pairings) Lets talk about first world problems for a minute. There are some that I am ill-equipped to help with: things like ‘oh no, my new smart phone has a glitch’ or ‘I have too many computers’ or ‘my shiny car is sooohoooo last season’. But then there are areas where I can be quite useful. Things like ‘I don’t know what to wear’ or, in this case, ‘oh no, I have too much rhubarb’. Yes, friends, too much rhubarb is an area where I can be useful indeed. You see in the last two weeks alone, I have made rhubarb syrup, rhubarb compote and rhubarb fool (then all of these with rhubarb and strawberries combined, though I will admit to preferring rhubarb alone where you can taste all of its rhubarby glory, unadulterated with the sweetness of the strawberry). All of these I could gladly share.
But my crowning glory, the barb on my rhu, would have to be rhubarb, elderflower and custard tart. For what two things go better together than rhubarb and custard? Apples and blackberries? Lysander and Hermia (which would be the worst name ever, given its similarity to hernia)? Barbecues and beer? No, rhubarb and custard is one of those matches that, in my opinion, is star-crossed from the beginning. Were I the type of person who thought that the natural world existed solely for our disposal, I’d be inclined to also believe that rhubarb exists solely for the purpose of being paired with custard. But that’s like saying that a woman who is a good cook exists solely for the purpose of feeding her husband. As in, outrageous.
Over the past couple of years, my friend Butter and I must have sent each other close to a thousand emails. Some short, some long, the majority discussing food, herbs and foraging. It was a fated friendship- both of us were looking to broaden our horizons a bit- she to learn about how to her use foraged food for medicine, and me just starting to realise that wildcrafted herbs could also be edible. It spawned a Wild Things roundup, that Butter still does monthly, and countless ideas being tossed back and forth, of interesting and delicious ways to use wild foods and herbs, and a friendship of immeasurable value. Where Butter knows food, I know medicine. Where Butter is reliable and steady, I'm like a bouncy ball (ie. not very steady). Where Butter has almost unlimited stamina (like a turtle), I need a nap after a sprint (like a hare). We, in my opinion, make a really good pair. In one of those many emails last week, we discovered that we were both making a similar dessert (please re-read treatise on perfection of rhubarb and custardy things for explanation of how such things happened) and decided to post them together. A reunification of forces. Which makes me extremely happy. So here's to friendship, and good ideas, and perfect pairings. Here's Butter's Rhubarb Elderflower Sour Cream Pie .<3
ps. If you do anything this week, make this tart. Your stomach and all your neighbours will thank you. Promise.
Rhubarb and Elderflower-Infused Custard Tart.
1 portion basic sweet tart crust
1 lb rhubarb 1/2 cup sugar
1/2 cup fresh elderflowers, or 1/4 cup dry 2 cups milk 1/2 cup sugar 3 egg yolks 2 whole eggs 1/4 cup tablespoons cornstarch 4 tablespoons unsalted butter 1 pinch salt 1 tsp vanilla or a pinch of vanilla powder
Make up the tart crust in advance, placing it in the fridge to chill for a couple of hours before you roll it out. Roll it out and drape it over a 9" tart pan, poke little holes in the bottom with a fork, then bake at 350 for about 25 minutes, until golden brown and beautiful.
Meanwhile, start the custard. Put the milk and elderflowers in a saucepan, and heat up the milk gently until it's hot to the touch. Switch off and leave to steep for 30 minutes to an hour. The flavour of the elderflowers will infuse in the milk. Strain out the flowers, and return the milk to the pan. Add the sugar, vanilla, and salt, then start to heat again, until the sugar is dissolved. In a separate bowl, whisk together the cornstarch and the eggs until smooth. Add a couple of big spoonfuls of the warm milk to the egg mixture, give it a stir, then add back to the saucepan and return to the heat. Bring to a boil, slowly, stirring or whisking constantly- don't let anything stick to the bottom. It'll start to thicken. Once boiling, stir vigorously for about a minute, then remove from the heat and stir in the butter. Put it in a bowl, cover with cling film, and allow to cool completely.
Cut the ends off the rhubarb, and cut each piece so that its about 5" long. More or less. Put all the rhubarb in a big pan, dust with the sugar, and sprinkle with water- about 1/3 cup for the whole lot. Put in the oven at 400 for about 20 minutes, until the water is gone and the sugar has gone caramelly and the rhubarb is looking cooked but not mushy yet (if you have a distaster and it goes mushy completely, it doesn't matter, just make a different design). Allow to cool.
With all your pre-cooked and cooled ingredients, assemble the tart. Spread the custard in a thick layer over the bottom of the tart, then decorate the top with rhubarb. You can serve it immediately, though I think it tastes better after a few hours.
