Ingredients :

• Nopal — This is the flat paddle of the prickly pear tree—the cactus vegetable. Choose a tender, bright green paddle, without brown spots or softness. The spines are normally removed before sale, but still run your hand over it carefully, a few often remain. If you can’t find fresh, jarred nopal exists—rinse it well before use, as it is often preserved in brine.
• Lemon — Fresh is mandatory. Bottled lemon has a flat and slightly chemical flavor that ruins the whole point. A bright yellow lemon, heavy in the hand, gives enough juice for one serving. For this tonic, a generous dose is better than a timid one—it’s the lemon that gives the character.
• Ginger — Optional but really good. A piece of 1 to 2 cm is enough—it brings a slight warmth and a little zing in the aftertaste that contrasts with the freshness of the lemon. If you are sensitive to spices in the morning, start with half.
• Honey — Not mandatory if you like pure acidity. A teaspoon of liquid honey—preferably acacia honey, it is discreet—is enough to round off the edges. Stevia also works if you prefer it sugar-free.
