As my wife is called Louise this my go to. Sweet, slightly tart and girly, she loves them. As passion fruit are so much more readily available now this is a good one. Ten years ago this would have been the province of cocktail bars only. The only change I have made is to use Disaronno as the amaretto. Otherwise made as is.
While looking for decent stirred cocktails I discovered this one. Using a decent spanish brandy as a base (At least Fundador!) and starting upwards. First tried Pain D'Epice in with Frangelico in absence of Creme de Noyauy, but settled without the Pain as it was too sweet. Initialy did this martini style as I am not a great fan of too diluted drinks. So far find this nicely nutty and not hideously sweet. As I refine I will report back. Could this cocktail be a platform for other nut based drinks?
