Wanted: dedicated educators willing to stoke open flames: A plug for a firebug-themed charter school? Almost. Or… just a perfectly innocent chance to teach kids the ins and outs of the 18th Century kitchen. Prospect Park’s well-preserved (and always educational) Lefferts Historic House is seeking three volunteers for its Hearth & Oven program. Volunteers will maintain fires, demonstrate cooking and help students and families “prepare foods using traditional tools and methods.” And, you’ll get to sample whatever charred Revolutionary-era delicacies are pulled from the flames. It requires prior experience teaching or cooking, and it’s billed as the perfect opportunity to learn a “unique skill.” Flames will be lit in July and will last for six weeks.
