Luscious Lemon & Passionfruit Butter: A Taste of Sunshine

I remember the first time I tasted lemon butter – it was at a small village fete, spread thickly on a still-warm scone. The tang, the sweetness, the luxurious smoothness… it was pure sunshine in a jar. Now, years later, the memory still makes me smile, and this lemon and passionfruit butter takes that sunshine to a whole new level. The passionfruit adds a tropical twist that’s simply irresistible, perfect for brightening even the dullest day.

Recipe Overview

• Prep Time: 5 minutes
• Cook Time: 15 minutes
• Total Time: 20 minutes
• Yields: 2 cups
• Serves: 10-20
• Dietary Type: Vegetarian

Ingredients

• 4 eggs
• ¾ cup sugar
• 125g butter, chopped
• 6 passion fruit, pulp only (discard the skins)
• 3 lemons, juice of
• ¼ cup water
• 1 teaspoon lemon zest

Equipment Needed

• Heatproof bowl
• Whisk
• Saucepan
• Wooden spoon
• Sterilized jars

Instructions

1. In a heatproof bowl, whisk together the eggs and sugar until well combined. Ensure there are no streaks of egg yolk remaining. A thorough whisk at this stage helps create a smooth, emulsified base for your butter.

2. Place the bowl over a pan of gently simmering water, creating a double boiler (bain-marie). The water should not touch the bottom of the bowl. This gentle heat prevents the eggs from scrambling.

3. Gradually add the remaining ingredients – the chopped butter, passion fruit pulp (discarding the skins), lemon juice, water, and lemon zest – to the egg and sugar mixture in the heatproof bowl. Adding the butter gradually helps it melt evenly and incorporate smoothly.

4. Whisk continuously over low heat for 10-15 minutes, or until the mixture thickens. The butter is ready when it coats the back of a wooden spoon and leaves a clear trail when you run your finger through it. Be patient; don’t rush this step.

5. It is vital to ensure the water remains at a gentle simmer and that the mixture doesn’t boil, as this will cause the eggs to curdle, resulting in a grainy, less desirable texture. Keep a close eye on the heat and adjust as needed.

6. Once thickened, immediately pour the hot butter into sterilized jars. Fill the jars, leaving about ½ inch of headspace at the top.

7. Seal the jars tightly while the butter is still hot. This helps create a vacuum seal as the butter cools, prolonging its shelf life.

8. After sealing, allow the jars to cool completely on the counter before labeling and storing.

Expert Tips & Tricks

• Sterilizing Jars: To sterilize your jars, wash them thoroughly in hot, soapy water, rinse well, and then place them in a preheated oven at 250°F (120°C) for 10 minutes. Alternatively, you can boil the jars in water for 10 minutes. Make sure the lids are also sterilized.

• Smoothness is Key: If you find your lemon and passionfruit butter isn’t perfectly smooth, you can pass it through a fine-mesh sieve after cooking to remove any lumps.

• Passionfruit Power: The flavour of passionfruit can vary in intensity. If your passionfruit is particularly tart, you may want to add an extra tablespoon or two of sugar to balance the acidity. Taste as you go and adjust accordingly.

• Preventing Curdling: The biggest risk is curdling the eggs. Constant whisking and a gentle heat are essential. If you see the mixture starting to curdle, immediately remove the bowl from the heat and whisk vigorously until smooth. You may be able to salvage it, but it’s best to avoid curdling altogether.

Serving & Storage Suggestions

This lemon and passionfruit butter is incredibly versatile. Serve it spread on freshly baked scones, muffins, toast, or croissants. It’s also delicious as a filling for cakes or tarts, or as a topping for pancakes and waffles. It makes a wonderful addition to a cheese board, adding a touch of sweetness and acidity to complement savory flavors.

Store the sealed jars in a cool, dark place for up to 2 weeks. Once opened, refrigerate immediately and use within 1 week. Refrigeration will thicken the butter further, so you may want to let it sit at room temperature for a few minutes before serving to soften it slightly. It is not recommended to freeze this butter, as the texture may change upon thawing.

FAQs (Frequently Asked Questions)

Q: Why is it important to use sterilized jars?
A: Sterilizing the jars prevents the growth of bacteria and extends the shelf life of the lemon and passionfruit butter, ensuring it stays fresh and safe to eat for longer.

Q: Can I use a different type of citrus fruit?
A: Absolutely! You can experiment with different citrus fruits like limes, oranges, or grapefruits to create unique flavor combinations. Adjust the sugar amount as needed, depending on the acidity of the fruit.

Q: How do I know when the butter is thick enough?
A: The butter is ready when it coats the back of a wooden spoon and leaves a clear trail when you run your finger through it. It should have a consistency similar to custard.

Q: Can I make this recipe without passion fruit?
A: Yes, you can omit the passion fruit for a classic lemon butter. Simply use the same amount of lemon juice and zest, and adjust the sugar to taste.

Q: My butter curdled. What did I do wrong?
A: Curdling is usually caused by overheating the mixture or not whisking constantly enough. Make sure to use a gentle heat and whisk continuously to prevent the eggs from scrambling. If it does curdle, try removing it from the heat and whisking vigorously to see if you can salvage it.
