It’s the most wonderful time of the year…rhubarb season! I know it’s a polarizing ingredient, but I can’t seem to get enough of it. I must confess, I’m a rhubarb hoarder. I buy way more than I can possibly consume, and I freeze it so that I will have rhubarb all winter long. 

How to freeze rhubarb: Wash the stalks and cut into 1-2 inch lengths. Line a baking sheet with parchment and arrange the cut rhubarb in a single layer. Place baking sheet in freezer until rhubarb is solidly frozen, a few hours. Transfer rhubarb to a freezer zip-loc bag.

How to use frozen rhubarb: Preheat oven to 350°F. Take equal parts of frozen rhubarb and frozen strawberries and place them on a parchment lined baking sheet. Sprinkle with 2-3 Tablespoons of sugar and roast for 20 minutes, until all soft and jammy. Mash with a fork of potato masher and transfer to a jar for storage. I like to mix it into my morning yogurt or use it as a filling for pastries, like strawberry-rhubarb hand pies. It keeps in the fridge for about 10 days. 

Difference between field-grown and hot-house rhubarb: The first rhubarb to hit the market in spring is hot-house rhubarb. Hot-house rhubarb is pink in colour while field- grown is red, streaked with green. The hot house rhubarb retains that gorgeous pink colour after cooking while the field-grown turns a dull brownish colour after cooking. The final difference is the texture. Hot-house is silkier, and less stringy than the field-grown.

Tartine is defined as an open faced sandwich, usually on toasted bread. It has come to mean “fancy toast”, as made popular by the charming Carrie Baird, one of my favourite cheftestants on Top Chef. And if you’ve been following me for a while, you know that fancy is how we roll around here.

Today’s tartine is homemade ricotta spread onto toasted crusty bread, topped with gently roasted rhubarb. If you have never made your own ricotta, I urge you to give it a whirl. Watching milk, salt and lemon, transform into ricotta cheese is pure culinary alchemy. If you are a food nerd like me, you will find the process quite thrilling. Of course store-bought ricotta can be used. I suggest whisking it with a few tablespoons of heavy cream to get a silkier texture.

This tartine would be delicious to serve with cocktails or with a salad for a light lunch. If I were going to have it for breakfast, I’d leave out the pickled onions and arugula and add some fresh mint. It’s eminently customizable.
