Milk

Milk is a high-calcium beverage that slightly replenishes Link's health. In both Ocarina of Time and The Minish Cap, it comes from Lon Lon Ranch, in Majora's Mask it comes from Romani Ranch, There are three types "Lon Lon Milk" "Romani Milk" and "Chateau Romani". 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 can be obtained directly from the cows found inside some secret grottos or in the two ranches. After playing Epona's Song to a cow, it will speak to Link, saying:

"Moooooooooo! What a nice song... It reminds me of the pasture... That song makes me feel so good, I can produce a lot of milk! Have some of my refreshing and nutritious milk!"

Milk is served in Milk Bars in Clock Town in Majora's Mask and on Mercay Island in Phantom Hourglass; however, it cannot be purchased in Phantom Hourglass.

Milk returned in Twilight Princess. In this game, it was goat milk. One serving restored three hearts.

Trivia

 * Young Link drinks Milk when taunting in Super Smash Bros. Melee. It also appears as a trophy.
 * The café on Windfall Island in 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.
