Jalapeño
From Memory Alpha, the free Star Trek reference.
Jalapeños are small Earth chili peppers distinguished for their "heat" or extreme spiciness when eaten. Cooks often used jalapeños as an ingredient in some dishes or as a garnish.
Jalapeño peppers were a main ingredient in Rodeo Red's Red-Hot, Rootin'-Tootin' Chili. When Neelix made such a chili on USS Voyager in 2374, he used a few too many and some crewmembers experienced heartburn and had to visit sickbay. The proper pronunciation of jalapeños is "ha-luh-PANE-yo". Neelix however pronounced it "jal-ap-anos". (VOY: "Message in a Bottle")
