A couple of shots of bready genever with a spoon of sugar and a couple of dashes of bitters - incredibly simple, equally classic, and with the right genever...
I've now tried this with oude and jonge genever - for science! It makes two very different drinks, both excellent. With oude it has more depth (but you really have to like that maltiness), with jonge it's fresher, and the bitters stand out more.
This was perfect for an afternoon tipple. The mixture of the Genever and bitters gives the cocktail a decided herbal taste, but soft. Sugar syrup adds a touch of sweetness, but the gin flavour is what is front and center with this cocktail.
If you select the gin of your choice in "Your Ingredients" which is found under the Cocktail Builder tab above, then that gin will display in all recipes you view.
