Ingredients

2 lemons 

2 cups sugar 

2 cups water 

2 sprigs rosemary 

Preparation

With a vegetable peeler, remove the peel from lemons, leaving bitter white pith behind. Combine peel plus remaining ingredients in a medium saucepan. Bring to a simmer, stirring, until sugar is dissolved. Remove from heat and let cool. Strain through a fine sieve (discard solids), and chill.
