Start by washing your oranges thoroughly. Then zest them—this is where the magic begins. The zest releases all those fragrant oils. Next, juice them until you’ve got a good amount of liquid. Both the zest and juice are essential for maximum flavor.

In a mixing bowl, combine the softened butter, demerara sugar, and golden caster sugar. Beat these ingredients until they are fluffy and light. This will create the perfect base for your marmalade.

Crack in the eggs one at a time, making sure each one is fully incorporated before adding the next. This will ensure a smooth mixture.

Now, sift the self-raising flour, ground almonds, and salt into the bowl. Gently fold the dry ingredients into the wet mixture. Be cautious not to overmix; you want it to be just combined.

Fold in the orange zest and juice. The vibrant color will have you daydreaming of sunny afternoons even in the winter weeks.

Preheat your oven and grease your baking tin with a bit of butter. Pour the mixture into your prepared tin, smoothing it out for even cooking.

Pop it into the oven and bake until golden brown and a toothpick comes out clean. The aroma will definitely fill your kitchen, creating an irresistible atmosphere.

Let your marmalade cool before you dive in. Once cooled, you can store it in jars for future enjoyment.
