small batch?

[robby6pack]

I posted this in the wrong place earlier. All help is appreciated.

I'm not going to get into what I'm brewing, but it's about the only thing my wife will drink. My question is if I want to brew 2.5 gallons from a 5 gallon recipe, is it as simple as cutting everything in that recipe in half? Might sound silly, but there might be something really odd out there that people might know. I would assume that the boil times would be the same. Anyone have the answer, or small batch brewing in general?

Put the original recipe into Brewers Friend. Take all of the numbers, gravity percentages, IBU, etc. then set the recipe to your required size. Adjust all of the numbers down until they match.
