Cuisine Type: 

A dazzling presentation befits this tangy, sweet and light-as-air mousse. This dessert is a fitting end to a fine meal.


1 tbsp. unflavored gelatin
1⁄4 cup light rum
1⁄3 cup fresh lime juice
1 tbsp. finely grated lime zest
3 eggs, separated, at room temperature
1⁄2 cup sugar
Pinch salt
3⁄4 cup heavy cream
1⁄4 tsp. mint extract (optional)
Graham cracker crumbs
Slivered lime peel
Sliced star fruit
Brown sugar
Shell-shaped chocolates


1. Sprinkle gelatin over rum in small saucepan; let soften for 1 min. Stir in lime juice, zest, egg yolks, and 1⁄4 cup sugar. Place over low heat and stir constantly until thickened.

2. Transfer mixture to a metal bowl set in a bowl of ice water. Cool, stirring occasionally, until thickened but not set.

3. Beat egg whites with salt until soft peaks form. Beat in remaining sugar, 1 tbsp. at a time, until whites form stiff peaks. Stir one-fourth the whites into lime mixture; gently but thoroughly fold in remaining beaten whites.

4. Beat cream until stiff; fold into lime mixture with mint extract until well blended. Spoon into stemmed glasses and sprinkle graham cracker crumbs around the outer edge. Garnish with slivered peel and sliced star fruit.

5. For presentation, spoon brown sugar on plate to resemble beach sand; arrange chocolate shell candies on top. Place glasses of mousse on plates.

lucretia chancler

Lucretia Chancler’s roots lie in Louisiana’s St. Landry Parish. She grew up in the parish, and her mother taught in the school district for 33 years—even occasionally teaching young Lucretia. Advanced degrees and a post-grad job took her to Colorado, Georgia and other places, but St. Landry soon called Chancler back home.

In October 2009, Chancler returned to Louisiana to become St. Landry’s supervisor of child nutrition. The parish’s economic makeup is a big driver behind Chancler’s local mission: More than 85% of the 14,000 students at the parish’s 32 schools are eligible for...

Menu Development

Last October, we published the results of FoodService Director’s first annual Chefs’ Council Menu Trends survey, revealing predictions for menu shake-ups in 2016 . Many of the predictions panned out, including an increase in snacking, ever-spicier flavor profiles, veg-centric plates, fresh-pressed juices and build-your-own options. Now we’re back with next year’s forecast, culled from our panel of 50 Chefs’ Council members—culinarians representing the core segments of noncommercial foodservice. Some of the flavors, ingredients and cuisines expand on current trends, while others go off in...

Ideas and Innovation

We wanted to add sushi, but that’s not really my expertise. So we found a great local company that offered to put three sushi chefs on-site every day. They supply the ingredients, and if we meet the minimum revenue each week, than we receive a percentage of sales. We have been exceeding the weekly minimum sales, which we track in our POS, in two days.
