Start with the jam. Add the sliced tomato, apple cider vinegar and sugar to the saucepan and heat on high. Let the mixture come to a boil, stirring frequently. The tomatoes will start releasing all of their moisture, so keep letting the mixture boil until it reduces by at least half, about 5 minutes. The mixture should be more viscous and sticky. Smash any remaining tomato chunks as it cooks. Then remove from the heat and set aside to cool.
1 cup cherry tomatoes, 2 tbsp apple cider vinegar, 1 tbsp granulated sugar
Make the pesto if you are making it fresh. Combine all the ingredients to a food processor (see below for recipe) and pulse until combined.
¾ cup fresh pesto
Add the ricotta cheese to a blender. Add the salt and water. Blend on high for about 15 seconds, until the mixture is smooth, whipped and creamy.
3/4 cup ricotta cheese, 1 pinch salt, 1 tsp water
Assemble! Start by adding a layer of pesto to your dish, followed by a layer of ricotta. Smooth it out carefully with a spoon to completely cover the pesto layer. Then carefully dollop the tomato jam across the ricotta, and use a spoon to smooth that out into an even layer as well. Enjoy!
