✨ Intro
We all know the struggle—finding a sweet treat that feels indulgent but doesn’t blow your daily syn count. This Slimming World Lemon Mousse? It’s the answer. It’s cool, creamy, citrusy, and incredibly satisfying, especially on hot days.

👨🍳 Step-by-Step Cooking Guide
🍶 Step 1: Make Jelly Base
Dissolve your sugar-free lemon jelly in hot water. Stir until every crystal is gone.
Tip: Use a jug or bowl with a spout to make pouring easier later.
❄️ Step 2: Cool It Down
Add cold water to bring the temp down before adding yogurt—this prevents curdling.
🥣 Step 3: Whisk In Yogurt
Add your fat-free yogurt and whisk well until smooth and uniform.
Tip: Use a balloon whisk or hand mixer for an airier mousse.
🍋 Step 4: Flavor Boost (Optional)
Add a bit of lemon zest if you love that zesty punch. A pinch goes a long way.
🧊 Step 5: Chill
Pour the mixture into ramekins or bowls. Chill in the fridge for at least 1 hour.
Tip: Leave overnight for the best texture and flavor.
🍓 Step 6: Serve & Enjoy
Top with berries, mint, or aerosol cream if you want to fancy it up—just count syns accordingly.

❓ FAQs
Q: Can I use flavored yogurt?
A: You can! Just ensure it’s fat-free and count any added syns.
Q: My mousse didn’t set—what happened?
A: The jelly may have been too hot when yogurt was added, or not enough jelly was used. Make sure to cool the jelly mix before adding yogurt.
Q: Can I use quark instead of yogurt?
A: Absolutely. Quark makes it a bit thicker and more tangy—delicious!
Q: Can I double the recipe?
A: Yes! Just double all ingredients and use a larger container or dish.
