Are you looking for a bright, stunning, and delicious treat that’s perfect for the warmer months ahead? If so, TikToker Lauren Nagel (@bonappeteach) is introducing an easy 3-ingredient dessert recipe called lemon posset. All you need are lemons, sugar, and cream—and you’ve got yourself an unbelievably yummy treat!

Originally, possets were used for medicinal purposes. It was a drink consisting of hot milk curdled with ale, wine, or another type of alcohol. It was often flavored with spices.

Nowadays, most modern versions of possets use citrus, like this lemon posset. Here’s how to make this dessert for your next gathering. Just a reminder: Mother’s Day is coming up!

Ingredients:

  • 4 large lemons
  • 2 cups of heavy cream
  • 1/2 cup of granulated sugar
  • 1 tablespoon of zest

Directions:

To make the lemon cups, start by cutting the lemons in half widthwise. Use a spoon or small knife to carefully scoop out the flesh.

Be sure not to puncture the rind. Save the lemon flesh, squeeze out the juice from it, and strain it into a bowl or cup. Set the juice aside for the filling later.

Place the halved lemon cups onto a plate or tray so that they are sitting upright. Next, make the lemon posset. Combine the heavy cream, sugar, and lemon zest into a medium-sized saucepan over medium heat.

Stir the mixture occasionally until it comes to a gentle simmer. Let it bubble lightly for three minutes as you continue stirring.

Then, remove the pan from the heat and whisk in the lemon juice slowly. The mixture will begin to thicken naturally.

Now, it’s time to fill the lemon cups! Pour the warm posset into the prepared lemon cups. If you don’t want to use halved lemons, you can opt for small jars instead.

Transferring the posset to a measuring cup with a pour spout makes it easier to fill the lemon cups without making as much of a mess.

Allow them to cool at room temperature for about 30 minutes. Then, refrigerate them for at least 2.5 to three hours or until they have fully set. You can garnish with decorative sugar and a raspberry before serving.

Three ingredient ? Lemon Posset UPDATE: This recipe requires these 3 exact ingredients to work. They interact and cause a chemical reaction to get the end result. If you use a different style sweetener it may not set. If you need a dairy alternative I’d encourage you to look up a vegan version of this dish as it would require other ingredients to work. Here’s what you need? 4 large Lemons for juice and cups (6 tbsp of juice) 2 cups Heavy Cream (this cannot be substituted for anything else- it’s essential for the recipe) 1/2 cup Granulated Sugar 1 tbsp Lemon Zest *I topped mine with decorative sugar and a raspberry* Prepare the Lemon Cups: Cut the lemons in half widthwise. Using a spoon or small knife, carefully scoop out the flesh and juice, being careful not to puncture the rind. Save the inside flesh of the lemon, squeeze out the juices and strain into a bowl or cup and set it aside for the filling. Set the halved lemon cups onto a tray or plate so they are sitting upright and are stable. Make the Lemon Posset: In a medium saucepan over medium heat, combine the heavy cream, sugar, and lemon zest (if using). Stir occasionally and bring to a gentle simmer. Let it bubble lightly for 3 minutes, stirring frequently. Remove the pan from heat and slowly whisk in the lemon juice. The mixture will begin to thicken naturally as you do this. Fill and Chill: Carefully pour the warm posset into the prepared lemon cups (or into small jars if not using the cups). It helps to add the lemon posset filling into a liquid measuring cup with a pour spout for easier transfer. Let them cool at room temperature for about 30 minutes, then refrigerate for at least 2.5-3 hours or until fully set. Before serving, you can garnish with sanding sugar and a berry if desired. #lemonposset #lemon #easydessert #brunch #easterrecipes #mothersdayideas
