Wash the limes and cut them into slices. Add a little grated lime zest from a whole lime. But be careful: the lime peel is very bitter. If you like it bitter, you can add more abrasion.
Quarter the slices and place in a suitable container - depending on the amount, a large bowl can also be used here. Add 8 tablespoons of cane sugar and squeeze out the limes with a potato masher. Bring the water to the boil, pour over the limes and stir everything well.
The whole thing is now about 2 hours and let cool down. The limes are now fished out (e.g. with a small sieve). Personally, I like it when the pulp and the grated lime peel are still in the finished iced tea - alternatively, the pulp can of course also be sieved.
The iced tea can also be served very well as a non-alcoholic caipirinha. Add about 8 cl lime iced tea (preferably the version with pulp) and 4 cl ginger ales in a cocktail glass and fill up with crushed ice.
To garnish, dip the edge of the cocktail glass briefly in water and then in brown cane sugar. The cane sugar sticks to the edge of the glass. Last but not least, put a cut lime slice on the edge of the glass.
The Boss Kitchen editorial staff oversees content review, fact-checking, and recipe verification across the site. Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
