Shook out very nicely indeed Heidi. Thanks so much for the tip. And, as you say, "different drink", so we felt at liberty to call it 'Heidi's Limoncello Cream Delux'. Having added your 15ml lemon syrup and loved it, we decided to go a step further and added 7.5ml Montenegro Amaro. You be the judge but we think it adds depth. We're sure that you have your own luscious lemon syrup recipe but, just for the record, here's ours: heat 1 1/2 cups of lemon juice and 1 3/4 cups of white sugar in a pan; bring to the boil and simmer for ten to fifteen minutes to thicken a little; remove from the heat, add 1/2 cup lemon juice and allow to cool. Adding the juice at the end, to our taste, contributes a fresh zesty element to the deep and luscious boiled syrup. Best wishes.
Fantastic! I will add that oh-so-delightfully-named edition to my personal library! When I ran my syrup, I included the zest of two lemons in the juice and strained out after simmering. Gave it a lovely zing, but its also left me floundering for more lemon syrup cocktail recipes. I have one strong contender I will post soon, but there's not many in "the canon."
