In a small saucepan, gently warm the sweetened condensed milk over low heat. Do not boil. Add the lime zest, stir, and let steep for 3–4 minutes, just until aromatic. Remove from heat and let cool completely. This step adds citrus aroma without heaviness or bitterness.

Add the lime pulp, cooled lime-zest–infused condensed milk, cold water, sugar, and ice to a blender. Blend until completely smooth and creamy, about 30–45 seconds.
Strain the mixture through a fine-mesh sieve into a pitcher to remove any remaining fibers. This step is essential for a clean, silky texture.
Fill glasses with ice, pour over the Brazilian lemonade, and garnish with lime peel twists.
