Watermelon lemonade

For ➋ glasses*
6 cl fresh-squeezed lemon juice
12 cl fresh watermelon puree
3 tbs simple syrup
18 cl cold water**
ice

Make syrup by heating 1 part of sugar with 1 part of water. Let cool when the sugar is dissolved. (Use half the quantity of water, and add cold water to cool it quicker.)
Purée the watermelon, and strain through a coarse strainer to remove seeds.
Stir it all together and serve over ice.
Garnish with a thin watermelon or lemon wedge.

*Keep proportions when making more.
**Use half spritz water to add bubbles.
***Add dash of vodka to have a cocktail.
****Replace water with dry white wine to have a wine cocktail. Adjust sugar level, depending on dryness of wine.
