Mix the condensed milk, passion fruit puree and vanilla extract together in a large mixing bowl until well combined
In another mixing bowl, use an electric hand mixer, or a stand mixer fitted with the whisk attachment, to whip up the double cream to soft peaks
Gently fold the whipped cream into the condensed milk mixture using a spoon or spatula. Do this in two or three stages until you have a smooth mixture
Place the ice cream into a 2.5 litre tub. Drizzle the passion fruit curd over the top and use a knife or cocktail stick to swirl it around. Decorate with passion fruit seeds if you like
Put it in the freezer overnight or for at least 4 hours before serving. Store in the freezer for up to 3 months
Notes
You will need sweetened condensed milk for this recipe, do not use evaporated milk as it will affect the final result.
The best kind of cream to use is double cream, which has around a 48% fat content. As long as you are using a high fat content cream that will thicken when whisked, then this will not greatly affect the final result. Using single cream, or a lower fat cream, will affect the final result.
I used a passion fruit puree for this ice cream. Juicing passion fruits is a messy job and each passion fruit doesn't provide much juice, so you'd need loads to get enough for this recipe. Using a ready made passion fruit puree is much easier!
It’s best to use an electric hand mixer, or a stand mixer, to whisk up the double cream. It will take much longer by hand and require a lot of work!
I used my Homemade Passion Fruit Curd to swirl into the ice cream, you can also use a good quality shop bought version.
The vanilla extract is optional, don't worry if you don't have any to hand.
Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50).
For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.
