Technique
Start with less crushed ice than you think you need, blend until the mixture moves freely, then add more ice a handful at a time. That approach gives you control over the texture and avoids making the drink watery before it becomes smooth.
A margarita is a cocktail consisting of tequila, orange liqueur, and lime juice often served with salt on the rim of the glass.

This is a frozen, party-style Margarita built around limeade concentrate rather than the leaner shaken combination of fresh lime and syrup. The concentrate supplies both acidity and sweetness, while the tequila and triple sec keep the citrus flavor from disappearing after blending.

Use well-chilled glasses and pour as soon as the mixture is smooth. A half-salted rim is more useful than a fully salted one: each person can choose a salted or unsalted sip, and the limeade does not become overwhelmingly savory.
The most common problem is adding a blender full of ice at the beginning. Too much ice can leave dry chunks around the blades and mute the tequila; running the blender too long after it is smooth creates the opposite problem by melting the ice.
For a fruit version, replace part of the crushed ice with unsweetened frozen strawberries or mango. Keep the limeade, tequila, and triple sec proportions unchanged at first, then add more ice only if the fruit leaves the batch too loose.
These notes explain how to execute and adapt the recipe shown above. Ingredients and serving traditions vary, so taste and adjust thoughtfully.
