There's a great one today GINSTR Recipe from our friend Yannick Duyck from Brussels. The bartender is a member of the Belgian national team of bartenders (UBB) and bar manager at The Twelve Bar, Thon Bruxelles.
Thanks for the recipe to imitate at home: theCosmonauts!
Which raspberry jam you use is up to you. Yannick swears by the "Bonne Maman" available from us (see photo).
Shake all ingredients vigorously in a shaker on ice until the shaker is steamed up on the outside. Put in a glass and enjoy.
