Milk

Milk is a high-calcium beverage that slightly replenishes Link's health. In both The Legend of Zelda: Ocarina of Time and The Minish Cap, it comes from Lon Lon Ranch, and is called "Lon Lon Milk". Each bottle of milk has two servings. While it's not as powerful or as energizing as the Red Potion, it does the job of recovering Link's health with great taste.

Milk is served in Milk Bars in Clock Town in The Legend of Zelda: Majora's Mask and on Mercay Island in The Legend of Zelda: Phantom Hourglass.

Trivia

 * Young Link drinks Lon Lon Milk when taunting in Super Smash Bros. Melee. It also appears as a trophy.
 * The café on Windfall Island in The Legend of Zelda: The Wind Waker apparently serves Lon Lon Milk, as a chalkboard written in Hylian advertises it along with "Deku Seed Cake" and "Zora Coffee". There are also a few empty bottles in the Nintendo Gallery with "Lon Lon Milk" text.
