Strawberry Rhubarb Fool

Tart rhubarb and strawberries cooked into a quick compote, then rippled through vanilla whipped cream and mascarpone and topped with toasted almonds.

Why you'll love Strawberry Rhubarb Fool

A fool is one of the oldest and simplest desserts in English cooking: cooked fruit folded into whipped cream, nothing more. Rhubarb is the classic choice, and April is when its pink stalks first come to market. Cooked down with strawberries, a little orange zest, and allulose, it turns into a bright, tangy compote that ripples through clouds of vanilla cream.

The secret is contrast, and keeping it. The compote has to be fully cold before it meets the cream, or the cream melts and goes flat. A spoonful of mascarpone whipped in with the cream keeps the peaks soft and steady for hours, so the fool holds its ripples in the glass. Folding in just a few strokes leaves streaks of pink and white, tart and rich, in every spoonful.

It takes ten minutes of cooking, sets in the refrigerator while you eat dinner, and looks lovely in small glasses.

Quick overview: This Strawberry Rhubarb Fool takes 20 min of hands-on time and about 1 hr 30 min in all and makes 6 servings, each about 3/4 cup. You'll need a saucepan, a skillet, and a hand or stand mixer.

Ingredients

  • 3/4 lb rhubarb (about 4 stalks), leaves cut off and discarded, sliced 1/2 inch thick
  • 10 oz strawberries (about 2 cups), hulled, divided
  • 1/3 cup allulose, divided Label: allulose, and nothing else
  • 1 tsp finely grated orange zest
  • 2 tbsp water
  • a pinch of fine sea salt
  • 1 1/2 cups cold heavy cream Label: cream, with no gums or carrageenan
  • 1/2 cup cold mascarpone Label: cream, or cream and milk, with citric acid and nothing else
  • 1/2 vanilla bean, split and scraped
  • 1/4 cup sliced almonds

Instructions

  1. Cook the compote: Chop a third of the strawberries and put them in a saucepan with the rhubarb, 1/4 cup of the allulose, the orange zest, water, and salt. Bring to a simmer over medium heat and cook, stirring often, for 8 to 10 minutes, until the rhubarb collapses into a thick, jammy compote. Rhubarb breaks down quickly once it heats through, and medium heat matters here because allulose browns faster than sugar.
  2. Chill the compote: Spread the compote in a shallow dish and refrigerate it for about 30 minutes, until completely cold. Warm compote melts whipped cream on contact, so this step decides whether the fool stays airy.
  3. Toast the almonds: While the compote cools, toast the almonds in a dry skillet over medium heat, shaking the pan, for 3 to 4 minutes, until golden. Tip them onto a plate to cool.
  4. Dice the berries: Dice the remaining strawberries into small pieces. Fresh berries folded in alongside the cooked ones give the fool a juicy bite.
  5. Whip the cream: Whip the cream, mascarpone, vanilla seeds, and the remaining allulose in a large bowl with a hand mixer or a whisk until it holds soft, billowy peaks. Stop there: cream whipped past soft peaks turns grainy when you fold it. The mascarpone gives the cream body, so it holds its shape for hours.
  6. Fold and set: Spoon most of the cold compote and the diced berries over the cream and fold with a spatula in three or four strokes, just enough to make thick pink ripples. Layer it into six small glasses with the rest of the compote, and refrigerate for 30 minutes, until lightly set. Scatter the almonds over the top just before serving.

Storage and leftovers

Cover and refrigerate the fool for up to 2 days. The cream softens and the ripples blur a little by the second day, and it still tastes good.

The compote alone keeps in a sealed jar in the refrigerator for up to 5 days, or frozen for up to 3 months, so a fool is ten minutes away whenever you whip the cream.

Variations

  • Yogurt fool: Fold 1 cup of whole-milk Greek yogurt into the whipped cream for a tangier fool with more protein.
  • Ginger: Add 1 teaspoon of finely grated fresh ginger to the rhubarb as it cooks.
  • Raspberry rhubarb: Use raspberries in place of the strawberries for a deeper pink and a sharper tang.
  • Cardamom cream: Whip a pinch of ground cardamom into the cream in place of the vanilla.

Notes and tips

  • Discard the leaves: Rhubarb leaves are toxic, so cut them off completely and throw them away. Only the stalks are eaten.
  • Pick red stalks: Deep red stalks make the pinkest compote. Green stalks taste the same and cook to a softer, greener color.
  • Use frozen rhubarb: Frozen sliced rhubarb works well. Cook it straight from frozen and add 2 to 3 minutes to the simmer.
  • Chill the bowl: A bowl and whisk chilled in the freezer for 10 minutes help the cream whip faster and hold its peaks.

Nutrition and mindful eating

  • Heavy cream and mascarpone are the real fat in this dessert, and fat is what makes a small glass feel rich and satisfying.
  • Rhubarb is a vegetable, botanically, and its sharp tartness means the fool tastes bright and fresh with only a little allulose.
  • Strawberries bring vitamin C and fiber, and eaten with cream they sit comfortably with RESET360's pairing of fruit with fat.
  • Allulose sweetens with very little effect on blood sugar, and it is used sparingly here, the RESET360 way.
  • As you eat, notice how the tart fruit and the rich cream balance each other, and pay attention to how a small glass feels like enough, with no pull for a second helping later in the evening.

Frequently asked questions

Have a question about this Strawberry Rhubarb Fool? Start here, with the questions people ask most.

What is a fool?

A fool is an old English dessert of cooked or crushed fruit folded into whipped cream. Gooseberries and rhubarb are the classic fruits.

Is rhubarb a fruit?

Botanically it is a vegetable, a stalk like celery, though it is almost always cooked like fruit. Its tartness is what makes it so good with cream.

Can I make it ahead?

Make the compote up to 5 days ahead. Fold the fool up to a day before serving and keep it covered in the refrigerator, adding the almonds at the last minute.

Why is my fool runny?

The compote was still warm, or the cream was folded too much. Chill the compote completely and fold in just a few strokes.
