Summer in Vermont is idyllic, there’s no question. But I will admit one thing that is a teeny bit disappointing. The fruit season takes forever to get going here. Strawberries, which I think of as a May fruit from my Illinois days, aren’t ready for picking until mid to late June. And the rest of the berries don’t even come around until July. So for a fruit pie lover in springtime here, it’s pretty much all rhubarb all the time. I was so excited when my daughter turned six months old in mid-June, that her first taste of solid food would be some uber-fresh tender summer produce from the Farmer’s Market. Imagine my dismay when I went there and saw nothing but plant starts, salad greens, and rhubarb. Spoiler alert: we gave her a banana instead, so it worked out OK.
Prepared well, rhubarb is actually pretty delicious, mouthwateringly tangy and so gorgeous with its pinks and reds fading into pale green. I fell in love with this rhubarb curd shortbread recipe I found on food52 a few years ago. I’ve made it tons of times and have developed my own tweaks and tricks so I’m sharing my adaptation of it here. It’s actually getting to be kind of like a game of telephone, this recipe – Rivka, who submitted it to food52, and has a terrific food blog of her own by the way, adapted it from Cook and Eat, who got the rhubarb curd recipe from Ginger Tablet. So I guess I’ve got a lot of chutzpah to think I can improve upon what all those actual food bloggers did. But seriously guys, my way is a leetle bit better. Kidding. Sort of. Not really.
So basically, you chop up a bunch of rhubarb and bung it in a pan with some sugar and a little water. While that’s cooking, go and make your shortbread. Throw a stick and a half of chopped up butter into your Cuisinart.
Have your three year-old sous chef add the flour for you.
Go check on your rhubarb. Whoa, a lot of juice has come out of it! Don’t worry, that’s normal. You want it to cook until it’s totally submerged, and soft enough to fall apart.
Now for the first genius part of this recipe. Spices in the shortbread. I would never have thought to combine spices like cloves, ginger, and cinnamon with rhubarb, but it’s perfect together. So perfect that I went ahead and made it even perfecter by adding two of my favorite dessert seasonings, cardamom and nutmeg.
Then dump it all into a baking pan and press evenly into a nice crust.
Chuck it in the oven on 350 and bake til golden. By now your rhubarb should be soft enough that you can do this to it just by mooshing with your wooden spoon.
Looks appetizing, doesn’t it? Once in a while I find rhubarb stalks that are red all the way up and create a beautiful pink puree. But more often than not, it looks like something out of a Gerber jar. Not pretty. So let’s call in a little of nature’s food coloring. Raspberries. I always have a bag in my freezer for smoothies, so I just made a tiny bit of raspberry coulis. Half a cup of frozen raspberries, a tablespoon of sugar, and some vigorous stirring over medium heat makes this:
When your shortbread looks like this, it’s ready to come out of the oven and cool on a rack.
While it’s cooling, mix together some egg yolks, sugar, and lemon zest. Add the rhubarb a scoop at a time and then place the bowl over a double boiler and for god’s sake, keep stirring. After about 5 minutes, it should be warmed through and thickened. I didn’t take any pictures of this part because the steam from the double boiler kept fogging my camera lens, but it looks pretty much like eggs mixed with sugar mixed with pink stuff. When it’s done, spread it over the shortbread and bake 10 more minutes at 350.
Droool… seriously you guys, these are so good my mouth is watering just thinking about them. I have one more left in the pan downstairs, I’d better go eat it before the kids wake up…
