A Tom Collins is probably as iconic an American cocktail as a Singapore Sling is to the Raffles Hotel though the latter might be younger by almost a century. Served in a tall glass to the traditions of a Tom Collins, Yuzu Collins at Kiyomi is Tanqueray gin, kakushigura shochu, yuzu juice, bitters and sparkling soda. Lacking in sugar sweetness, I suspect it might be a modern interpretation of the original.
