>>I suppose a slice of frozen lemon would work as well then<<

Yes I suppose that it would. It also helps if you keep the gin in the freezer too. They do that in Amsterdam. When you pour Dutch Gin straight from the freezer it has the consistency of syrup and you can fill the glass to the brim and beyond so that it forms a meniscus on the glass. For some reason this trick does not work quite as well with Gordon's. Pity that.
