On May 11 the rhubarb showed up in my backyard in downtown Whitehorse, heralding a new season of crisps, pies, jams and chutneys.
I look forward to weeks of roaming the yard, knife in hand, and when I’ve exhausted my own supply, moving into the alleys where it grows exuberantly along the fences. Garden rhubarb (Rheum rhabarbarum) is not an indigenous species in the Yukon; settlers brought it here. (As Yukon biologist Bruce Bennett once pointed out, a rhubarb patch in the bush is a reliable marker of a former dwelling place.)
The indigenous wild rhubarb (Aconogonon alaskanum) grows abundantly in parts of the Yukon, but it’s a different species, a member of the buckwheat family. Though the young stalks and leaves are edible (the leaves of garden rhubarb are toxic to humans) wild rhubarb doesn’t have quite the juicy, crunchy, sour appeal of garden rhubarb. Having a dish of wild rhubarb is like eating your greens, not your dessert.
Garden rhubarb is such a good producer the tendency is to just keep harvesting, resulting in a pile-up of chopped rhubarb in bags in the freezer. A hubbub of rhubarb!
This year, I’ve figured out what to do with the backlog: roast it. The idea came from a recipe by Posie Brien on the King Arthur Flour baking site. Roasted rhubarb is sweet, tart, rich, slightly caramelized—an entirely different beast from stewed rhubarb, a rescuer of freezer-burned rhubarb, and the last word in versatile. As Brien says, it can be mixed with yogurt or whipped cream for a quick dessert, layered with custard and streusel in a parfait, dolloped on your morning porridge, or used as a filling in all the old classics—pies, galettes, crisps, squares.
When cooked right down until it’s sticky, the texture and even flavour of roasted rhubarb is reminiscent of cooked dates, which suggests, of course, date squares. My mother had a repertoire of three desserts; family treasures she baked over and over again, and one of them was date squares. I went back to her recipe, actually her Mom’s recipe—I can still see Granny’s handwriting on the stained blue card—and adapted it to my new favourite rhubarb treatment. It worked beautifully.
Inspired by Posie Brien at kingarthurbaking.com These squares are fabulous just eaten in the hand, but if you want to get fancy, serve with a dollop each of whipped cream and rhubarb filling on the side. My mother’s/grandmother’s recipe is quite specific: the oats must be quick-cooking in order to get the right texture in the topping. I’ve tried with rolled oats and it ends up too crumbly. If you only have rolled, whizz them in the food processor a few times until the flakes are a quarter of the original size.
