Homemade Iced Limeade

I’m including a recipe for limeade rather than lemonade here, as it’s more unusual. Limes are slightly more perfumed then lemons and give a tanginess that is very moreish. Good homemade limeade should have a kick of refreshment, be tangy without being bitter, and be sweet enough that the limes don’t attack your throat. Mixed with chilled beer it makes a great shandy.
