If you’re looking for a dessert that’s equal parts elegant, refreshing, and fun to serve – this one’s for you. These Vegan Lemon Possets are smooth, creamy, and bursting with citrusy brightness. But what makes them even more special? They’re served right in lemon shells! It’s a beautiful little touch that turns a dessert into a showstopper.

What Is a Posset, Anyway?
Traditionally, a posset is a British dessert by curdling cream with lemon juice – no eggs, no gelatin, just a magical reaction between citrus and dairy. In this plant-based version, we’re swapping out the cream for a dairy-free alternative and giving it a little help with a natural thickener like cornstarch or agar agar. The result? The same silky-smooth texture and tangy-sweet flavor – but 100 % vegan.
Why Serve Them in Lemon Shells?
Not only do lemon shells look beautiful on a plate, but they also lightly infuse the posset with even more citrus aroma. It’s a creative and waste-reducing way to serve dessert – and your guests will love it. Plus, there’s something charmingly old-school about serving desserts in edible vessels, don’t you think?
