A Collins is a style of cocktail that is made in, as you might imagine, a Collin's glass. I'm going to show you how to make the king of all Collin's cocktails, Tom Collin's. The Tom Collins is basically a gin sour that is topped with soda water. So we're going to start with our gin. Two ounces, as you would a normal gin sour. You notice a lot of these classic cocktails have the same recipe's just different ingredients.
And we're just going to build this right in the glass, because we're going to top it with soda water. So we don't need to shake it or stir it to add any extra dilution from the ice. Just make sure that your soda is nice and cold, because we're not going to get any extra chilling from the ice when we shake it. Now three-quarter ounce of simple syrup as our sweetener, again just one part sugar to one part water.
And we need some lemon juice as our citrus to balance out that sweetener, we're just going to need three-quarters ounce of that, equal parts. And as always the fresher your juice is the better. I cannot condone store bought citrus. I just can't do it and I won't. All right, fresh lemon juice, three-quarters ounce of that. This drink is really great for hot weather, because of all that soda water it's really, really refreshing. And also, it makes it last a lot longer.
And of course, you can use three-quarters lemon. The Tom Collin's is the most classic of the Collin's, but it's a great template for variation. You could make this with bourbon. You could make this with tequila, all that stuff works. Now I'm going to top it off with ice. I really like to fill it all the way up and our nice cold seltzer. Whoop, we're good.
Like I said that'll serve as our dilution. So no shaking or stirring. I think the Tom Collins is a drink that deserves a good garnish. It's a long drink. You're going to be holding it for awhile, might as well make it pretty to look at, so okay I'm just going to cut a little wedge of orange. And if you have a toothpick or a little crystal pick like this you can make what they call a flag. And add a little cherry, with a cherry on top, naturally. And then jimmy that in there, and there you go, and that's how you make a classic Collins, the Tom Collins.
