Combine gin, Lillet blanc and cranberry shrub in mixing glass over ice, stir to combine, strain into flute, top with dry prosecco or cava.
From my notes, this was tasty last Thanksgiving with homemade cranberry shrub. Might be tasty with other shrubs (i.e. cherry, kiwi, apricot) for other occasions. Cranberry shrub homemade with demarara sugar & cider vinegar as per http://bit.ly/ekePOp
Whipped up à la minute last Turkey Day, 11/25/10.
