Try to find limes that are actually golden-yellow in color when shopping. The dark green limes you see are limes that have been picked unripe then gassed to guard that color. When limes are yellow and ripe, they have a softer flavor, with a hint of citrusy sweetness. Ethnic markets, especially those catering to Asians and Latinos, are great places to look for them. Key Limes, if you can find them, are the classic.
