I made this for the first time tonight using an Old Tom Gin -thinking the stone fruit notes would play well with the other ingredients - and a VSOP Calvados. The Old Tom might have a little less bite than a London Dry in this drink, but I was pleasantly surprised with the results. I kept Difford's ratios except I did 1/2 oz of homemade grenadine, same as Ryan. A lot better than I expected, but it sadly not very pink though lol.
