Ingredients

  • 24 g Powdered Gelatin (Bloom in water; use unflavored powdered gelatin)
  • 60 ml Water (For blooming gelatin)
  • 140 g Liquid Glucose (Half a cup; sold in tubes in the baking section)
  • 150 g Caster Sugar (Fine‑grained sugar for syrup)
  • 120 ml Water (For sugar syrup)
  • 2 tsp Vanilla Extract (Pure vanilla extract for flavor)
  • 1 cup Cornstarch (For dusting the finished marshmallows)
  • 1 cup Icing Sugar (For dusting the finished marshmallows)
  • 1 tsp Flavorless Oil (For greasing the tin; use a neutral oil such as vegetable oil)
  • 1 sheet Cling Film (To line the 8×8 tin)

Instructions

  1. Bloom the Gelatin

    Combine 24 g powdered gelatin with ¼ cup (60 ml) water in a small bowl, whisk briefly and let sit for at least 5 minutes until it becomes a grainy jelly.

    Time: PT5M

  2. Melt the Gelatin

    Place the bloomed gelatin in a microwave‑safe bowl and heat on high for about 30 seconds, then stir until fully liquid.

    Time: PT1M

  3. Prepare the Sugar Syrup

    In a deep saucepan combine ¾ cup (150 g) caster sugar, ½ cup (120 ml) water and half of the liquid glucose (≈70 g). Heat over medium heat, stirring until sugar dissolves, then attach the candy thermometer.

    Time: PT10M

  4. Heat Syrup to Target Temperature

    Continue heating the syrup until the thermometer reads between 112 °C and 115 °C (233‑239 °F).

    Time: PT5M

    Temperature: 112-115°C

  5. Start Mixer on Low

    While the syrup is heating, set the hand mixer with the whisk attachment to the lowest speed.

    Time: PT1M

  6. Combine Gelatin and First Half of Glucose

    Pour the melted gelatin into the mixing bowl, add the remaining half of the liquid glucose, and whisk on low for about 1 minute until smooth.

    Time: PT1M

  7. Add Hot Syrup to Mixer

    When the syrup reaches the target temperature, slowly drizzle it into the mixing bowl while the mixer runs on low.

    Time: PT2M

  8. Whisk on Medium‑High

    Increase the mixer speed to medium‑high and whisk for 5 minutes. The mixture will become opaque and increase in volume.

    Time: PT5M

  9. Whisk on High Speed

    Turn the mixer to the highest speed and continue whisking for another 5 minutes until the marshmallow mass is thick, glossy and holds stiff peaks.

    Time: PT5M

  10. Add Vanilla

    Add 2 tsp vanilla extract and whisk on high for an additional 2 minutes until fully incorporated.

    Time: PT2M

  11. Transfer to Prepared Tin

    Line an 8×8‑inch tin with cling film, grease lightly with flavorless oil, then quickly pour the marshmallow mixture into the tin and smooth the top with a greased spatula.

    Time: PT2M

  12. Dust the Surface

    Mix equal parts cornstarch and icing sugar (about 1 cup each) and generously dust the top of the marshmallow slab.

    Time: PT2M

  13. Set at Room Temperature

    Leave the tin uncovered at room temperature for at least 4 hours (or overnight) until the marshmallows are firm to the touch.

    Time: PT4H

  14. Unmold and Cut

    Remove the cling film, place the slab on a dusted surface, and cut into squares using a sharp knife that has been dipped in hot water and dried.

    Time: PT5M

  15. Final Toss in Dusting Mix

    Toss each marshmallow piece in the remaining cornstarch‑icing‑sugar mixture to coat all sides, then shake off excess.

    Time: PT5M

Frequently Asked Questions

Everything you need to know about this recipe

Q

What is the cultural significance and history of vanilla marshmallows in British confectionery?

A

Marshmallows originated from the ancient Egyptian use of the mallow plant, but the modern British version developed in the 19th century when gelatin replaced the plant extract. Vanilla‑flavoured marshmallows have become a classic sweet treat enjoyed at fairs, parties, and as a nostalgic snack.

cultural
Q

What are the traditional regional variations of marshmallows in British cuisine?

A

In the UK, traditional marshmallows are often plain or vanilla‑flavoured. Regional twists include adding rosewater in Yorkshire, whisky in Scotland, or lemon zest in coastal towns. Each variation reflects local flavour preferences.

cultural
Q

How is vanilla marshmallow traditionally served in British tea time culture?

A

Vanilla marshmallows are commonly served alongside tea, either on a platter with other sweets or floated in hot chocolate for a luxurious treat. They are also used to top desserts like strawberry shortcake or baked Alaska.

cultural
Q

What occasions or celebrations are vanilla marshmallows associated with in British culture?

A

Marshmallows are popular at birthday parties, Christmas markets, and summer fairs. They are also a favourite treat for children’s birthday celebrations and are often given as homemade gifts during holidays.

cultural
Q

What makes vanilla marshmallows special or unique in British confectionery?

A

The use of gelatin gives a firm yet airy texture that lasts longer than egg‑based recipes. Adding pure vanilla extract provides a clean, aromatic flavour that sets them apart from generic sugary sweets.

cultural
Q

What are the most common mistakes to avoid when making vanilla marshmallows at home?

A

Common errors include overheating the sugar syrup, which creates a gummy texture, under‑whisking the mixture so it stays grainy, and not greasing the tin properly, making unmolding difficult. Following the exact temperature range and whisking times prevents these issues.

technical
Q

Why does this vanilla marshmallow recipe use a candy thermometer instead of guessing the temperature?

A

The syrup must reach 112‑115 °C to achieve the right sugar concentration for a stable foam. Without a thermometer, the syrup can easily exceed this range, resulting in chewy, rubbery marshmallows.

technical
Q

Can I make the vanilla marshmallows ahead of time and how should I store them?

A

Yes, you can make them a day or two ahead. Keep the finished marshmallows in an airtight container at room temperature and store the dusting powder separately. For longer storage, freeze them in a single layer and re‑toss in dusting mix before serving.

technical
Q

What texture and appearance should I look for when the vanilla marshmallow mixture is ready?

A

The mixture should be thick, glossy, and opaque, having roughly doubled in volume. When lifted with the whisk, it should form stiff peaks that hold shape without dripping rapidly.

technical
Q

How do I know when the vanilla marshmallows are done cooking and ready to set?

A

When the whisked mixture becomes opaque, fluffy, and holds stiff peaks, and the syrup has reached 112‑115 °C, the marshmallows are ready to be poured into the tin and set.

technical
