Last week I wanted to make lemonade, but couldn't find a recipe I liked.
I tried to mix a few bits of recipes I could find, or remember, but this was delicious:
Zest the lemons and put that in 1 litre of water with 100 g sugar in a pan. Warm so the sugar dissolves, then cool. Seive out the lemon zest.
Juice the lemons and limes, and add to the cool syrup, and enjoy.
Now the borage is flowering, borage (aka starflower) in icecubes would be fun, or just drop a few flowers in the drink. I usually eat them in salads.
