How Does Lemon Posset Set

The lemon juice acidifies the cream, causing the casein proteins in the cream to clump. Think just like curds and whey. So when an acid is added to the cream the ratio of fat in the cream prevents the casein from clumping tightly, instead of curdling as milk would, the mixture thickens and sets into a solid creamy and luxurious filling not unlike the texture of a pana cotta.

Can I Change The Biscuits Used

We’ve used a ginger nut biscuit that is a hard, dark little bikkie flavoured with powdered ginger. You know the type you would almost crack a tooth with they’re so hard but the perfect biscuit to dunk into a cup of tea.

Initially, we wondered if the biscuit would set too hard once ground to a sandy texture and mixed with melted butter. Nope, the biscuit base is easily sliced once set and adds the perfect balance along with the lemon citrus flavour.

You can of course use a plain biscuit such as a digestive and add a teaspoon or so of powdered ginger, or leave the ginger out altogether.

In Australia we used Arnott’s brand ginger nut biscuits though elsewhere in the world you could use Marie, Shortbread, Oreos, Hobnobs or Graham crackers instead. You just won’t get the same flavour balance that the ginger nuts bring to the party. 😢

Just a Few Simple Steps

How To Make The Biscuit Base Crumbs

The quickest and easiest way to make the biscuit crumb is to use a food processor for the job.

Otherwise, you can place the biscuits into a plastic bag and use a rolling pin, meat mallet or another hard utensil to act as a hammer and bash away until you have an even sandy like texture.

Lining The Springform Tin

By lining the base and side of the springform tin with baking (parchment) paper allows you to easily peel the paper from around the sides to give you a smooth even side and the base paper allows you to easily slide the tart onto a serving plate for a professional-looking presentation.🧐

Making The Lemon Filling

Making the filling is an absolute doddle. All you’re doing is placing the cream into a saucepan along with the sugar and zest and heat gently until the sugar has dissolved. Then switch off the heat and allow the mixture to cool and infuse for 15 minutes then stir in the lemon juice. It’s that easy!

Allowing the mixture to cool and infuse releases the natural lemon oils from the zest into the posset, so please don’t skip adding the zest.

There seems to be a divide between those who like the little zest flecks and those who don’t. We decided we wanted a smooth filling so we strained the zest out before adding the lemon juice.

And Just Like That It’s Done! 😃

What To Serve With No Bake Lemon Posset tart

We love to serve fresh raspberries with this tart. The raspberries bring a slight tartness that balances beautifully with the sweet lemon flavour.

At times fresh raspberries can be woefully expensive so you could buy some frozen raspberries and thaw them then blitz until you have a puree.

Other berries that would work well are blueberries, blackberries or boysenberries.

Can I make This Lemon Posset Tart In Advance

You can make this lemon tart 2 days ahead and keep covered in the refrigerator still in the tin. Use a dinner plate to place over the tin as plastic wrap may cause condensation and drip onto the tart.

When you’re ready to serve remove the springform surround and gently peel the paper away. Lift the metal base and place it onto your serving plate and gently slide the paper base away.
