Monitor the lemon juice to taste. too little too sweet, too much too tart. A go to recipe

Great after dinner cocktail. I agree a bit sweet. I might recommend 15 ml of apricot brandy.

I recommend 1/2 amount of the single cream or 1/2 & 1/2

Simon your recipe list asks for 7.5 ml or 1.5 tbs 7.5 ml of matcha powder. Down below your annotation suggests 1/4 tsp or 1.25 ml of matcha powder which after following the instructions would be more appropriate. Also a dark carcaco is preferred as specified. I used a chocolate liqueur Borgata as a substitute which I would not recommend. I will restock and try again with dark Caraco and 1/4 tsp of matcha your published recipe should be corrected
