Citrus Soup Frappe

This is a delicate, slightly retro chilled dessert soup that belongs to the era of formal dinner parties and multi-course tasting menus. Bright citrus juices get bound with just enough gelatin to give the soup body without setting it firm, then enriched with red wine, golden Sauterne, and kirsch (cherry brandy) for a layered, perfumed flavor that’s miles from any breakfast smoothie.

The gelatin amount is everything. Too much and you’ve made jelly. Too little and it’s just spiked juice. The 1½ tablespoons here gives you a soft, almost frappe-like texture, like a slushy that holds its shape on the spoon for a second before melting.

Serve in chilled bowls with the orange sections suspended through. A small mint sprig on top adds color and a faint herbal lift.

Chef Tips

• Soften the gelatin in the cold wine first, then dissolve over hot water. Adding gelatin straight to warm liquid creates lumps.
• Use freshly squeezed orange and lemon juice, not from concentrate. The flavor difference is massive.
• Strain raspberry juice through cheesecloth or a fine mesh to remove seeds.
• Chill at least 4 hours, ideally overnight, so the soup sets gently.

Variations

• Substitute pomegranate juice for raspberry for a tart, jewel-toned version.
• Use sparkling wine in place of Sauterne for tiny effervescent bubbles in the finished soup.
• Skip the alcohol entirely and replace with extra orange juice plus a splash of grenadine for a non-alcoholic version.
