Cut strawberries in quarters lengthwise. Cut rhubarb into chunks approx. the size of strawberry quarters. Drizzle with honey and sprinkle with vanilla seeds. Mix well and roast in a preheated oven at 180°C for 10 minutes.
Remove from the oven and let cool.
Place all ingredients in a food processor and mix to get a smooth spread.
Mixing by hand: In a bowl, mix flour, sugar, salt, and vanilla. In another bowl mix milk, oil, and eggs. Add half of the liquid mixture and mix well to get a paste. Add the rest of the liquid and mix well. You will get a quite watery batter. Perfect for making thin crêpes.
Using a blender: Place all ingredients into a blender, adding the flour last. Mix until you get a smooth batter.
Leave the batter to rest for 30 minutes. You can store it in the fridge and use later.
After the batter has rested, heat a pan over medium-high heat. Once it is hot use a paper napkin or a brush to cover the pan with oil as thinly as possible.
Add the batter to the pan according to the pan size.
20 cm pan – about 3 tbsp of batter
25 cm pan – about 1/4 cup of batter
30 cm pan – about 1/3 cup of batter
The first crêpe is usually a tester to see how hot is the pan and how much batter you need for one crêpe.
Pour the batter in the middle of the pan and quickly rotate it to cover the whole surface. Almost immediately the edges will start to brown. That's when you take a spatula and go around the edges to release the crêpe. After the crêpe surface has set (meaning there's no glossy uncooked batter) turn it around with a wide spatula or by tossing it in the air. Cooking the first side should take about 30-40 seconds. Leave the crêpe to cook for an additional 10 seconds on the other side.
Repeat for the rest of the batter.
Stack the crêpes on a plate.
Serve warm with chocolate and hazelnut spread and roasted strawberries and rhubarb including the liquid from the roasting.
