Carefully, blend it together for 5-10 seconds on low. Note: Do not overlmix or it will get very bitter. It will be chunky.
Pour your drink mixture through a fine mesh strainer over a large bowl. Discard the lime pulp that is left over in the strainer.
After rinsing the blender, add the strained lime juice back in.
Now add the sweetened condensed milk to the blender. Then pulse 1-3 times until nice and frothy (do not blend too long).
Pour mixture over ice in a glass.
Garnish with additional fresh limes, if you are using them, serve, and enjoy.

Don't blend this drink for too long or it'll extra bitter. It's okay to have some chunks in it. This drink however does naturally have a touch of bitterness to it so keep that in mind before making this drink the traditional way. It's not for everyone.
Traditional limonadas are made with the lime peels on, but you can remove them if needed. Removing the peels will remove most of the bitterness.
Use ripe, plump limes if possible. If you need help picking out ripe limes, check out the FAQ section for some of our best tips.
If you keep the peels on the limes, you'll need to consume the drink immediately or else risk it getting more and more bitter as it sits.
