How to Melt the White Chocolate

Melting white chocolate is easier than you might think! The quickest way is in the microwave. This method works best because it keeps the chocolate from overheating while still melting it evenly. But if you prefer, you can absolutely use the double boiler method for more control. Either way, you’ll end up with smooth, silky white chocolate that’s perfect for coating and decorating.

1. For this recipe, I’m using a block of white chocolate—that’s what I can easily find at the supermarket. If you have chocolate buttons, they’ll melt even faster. Alternatively, you can chop the block into small pieces to help it melt more evenly.
2. Place the chopped white chocolate into a heat proof bowl. 
3. Microwave for 30 seconds, then take it out to stir. Then microwave it for a few 15-second bursts, stir thoroughly after each burst.
4. Microwave it until completely melted.

How to Temper the White Chocolate

White chocolate can be a little tricky to work with—it burns easily and can lose its shine if overheated. But with the half-and-half method, you don’t need a thermometer or fancy tools. It’s a straightforward way to get beautifully smooth, glossy chocolate that sets perfectly every time.

1. Chop half of the total chocolate needed (100g for this recipe) and melt it until smooth.
2. Add small portions of the remaining finely chopped chocolate into the melted chocolate.
3. Stir continuously as each addition melts, repeating until all the chocolate has been incorporated.
4. Continue stirring until the chocolate is completely smooth and uniform—this cools it down and brings it into temper, leaving it glossy with a perfect snap.

How to Colour White Chocolate

1. Use oil-based food colouring—gel colours won’t work due to the fat in the chocolate.
2. To neutralise yellow tones, mix in a tiny bit of Purple colouring.
3. Notice the difference: on the left, we’ve added Purple, while the right remains yellowish.
4. Separate the amount of chocolate you want to colour and add the oil-based food colouring a little at a time—a tiny bit goes a long way.

5. Gradually add oil-based food colouring to the chocolate, mixing well until the colour is even. For example, a few drops of Matcha can create this shade.
6. For orange (not included in the set), mix a few drops of Red with Yellow to achieve the desired shade.
7. Add Purple to create this shade.
8. Add a few drops of Black to achieve this shade.

How to Chocolate-Coat Madeleines

Working with chocolate can seem intimidating at first, but once you know the steps and tricks I’m about to show you, it’s actually very satisfying—and even a lot of fun!

1. Spoon about 1 tablespoon of melted/coloured white chocolate into each cavity of the madeleine pan. 
2. Place a (cooled) madeleine on top of the chocolate. Gently press and wiggle slightly so the chocolate spreads evenly across the shell. Leave the madeleine sitting in the pan and repeat for the rest. Transfer the whole pan to the freezer for 15 minutes, or until the chocolate is completely set.
3. Once set firm, simply push the madeleines out of the pan.
4. The shell side should be coated in a crisp and shinny layer of chocolate.

Helpful Tip: If a madeleine doesn’t come out with gently pressure, don’t keep p pushing too hard—it might break. Just pop it back in the freezer for a little longer, and it should release easily afterward.

Chocolate Coating Tricks

Working with white chocolate can be a little tricky—it can seize, harden too quickly, or develop streaks. But with a few simple tricks, the process becomes much easier and much more enjoyable.

Tip 1: Always keep the chocolate warm. I like to place the bowl of chocolate inside a larger bowl of warm water to keep it runny and prevent it from hardening too quickly.

Tip 2: Warm the madeleine pan before adding the chocolate. You can use a hair dryer to gently heat the metal moulds so that when the chocolate hits the pan, it won’t experience a temperature shock. Keeping the chocolate at a runny consistency helps achieve that smooth, glossy finish.

Tips for Working with White Chocolate

• Chop into small pieces – This helps it melt evenly and prevents burning.
• Use gentle heat – Melt slowly in a microwave in short bursts or over a double boiler.
• Avoid moisture – Even a drop of water can cause the chocolate to seize.
• Tempering optional but helpful – Adds shine and helps it set faster on madeleines.
• Keep it warm while decorating – Place the bowl in a larger bowl of warm water to prevent it from hardening too quickly.
• Adjust colour carefully – Use oil-based food colouring to tint white chocolate; gel colours won’t work.
• Neutralise yellow tones – Add a tiny bit of purple colouring if your white chocolate looks too yellow.

How to Make Royal Icing

Making royal icing is actually quite simple—you only need three ingredients and a hand-held mixer! With just icing sugar, meringue powder, and a little water, you can whip up a glossy icing that’s perfect for decorating. Don’t be intimidated—once you try it, you’ll see how easy (and fun!) it is to make at home.

1. In a mixing bowl, whisk together the icing sugar and meringue powder.
2. Add a few tablespoons of water and mix to combine.
3. Beat on medium speed until it comes together into a thick paste, then increase to medium-high.
4. Continue beating until the icing is glossy, shiny, and nearly doubled in volume.

Now you have your royal icing ready! At this stage, it should be very stiff, which makes it the perfect base. From here, you can adjust the consistency depending on your design needs—add a tiny bit of water at a time to thin it out, or mix in a little extra icing sugar to thicken. Small adjustments go a long way, so always work gradually.

How to Colour Royal Icing

Colouring royal icing is super simple—and really fun! Just a tiny bit of gel food colouring can transform plain white icing into any colour you can imagine, letting you get creative with all kinds of designs.

1. Always cover your royal icing with a damp cloth while working to prevent it from drying out.
2. When ready to colour, give the icing a quick stir to restore its consistency.
3. If you need to thin it, add a little water at a time—using a spray bottle helps control the amount better than spooning.
4. Add gel food colouring gradually with a toothpick. Since gel colours are highly concentrated, a little goes a long way, and you can always add more until you reach your desired shade.

5. Divide the royal icing into separate bowls—one for each colour. Gradually add gel food colouring to each bowl, mixing well until the colour is even. For example, a few drops of Violet can create this shade.
6. Electric Green for this shade.
7. Orange for this shade.
8. A few drops of Super Black for this shade.

9. The gel colours I used for this project: Super Black, Electric Green, and Orange are from AmeriColor, while Violet is from Wilton.
10. Transfer each coloured icing into a separate piping bag. Secure the top of each piping bag with a knot to prevent the icing from spilling while decorating.

Tips for Working with Royal Icing

• Check the consistency – Use slightly thick icing for designs that hold shape, and thinner icing for flooding or smoother coverage.
• Add water gradually – Adjust consistency a little at a time to avoid icing that’s too runny.
• Keep icing covered – Cover bowls with a damp cloth to prevent it from drying out while you work.
• Colour carefully – Use gel food colouring for royal icing; a little goes a long way.
• Work efficiently – Have all piping bags, tips, and colours ready before you start.
• Use a needle tool – Guide the icing on the surface for precise designs.
