ADD flour, eggs and salt into your stand mixer. MIX using low speed until the ingredients are somewhat combined. ADD red beet puree and a few drops of olive oil and continue mixing until a ball shape.
If you notice that the mixture is too wet, add more flour. On the other hand, if the mixture is too dry, add more red beet puree. APPLY the dough hook attachment to your blender.
Knead the dough until it's no longer sticky. REMOVE from the mixer and make a ball out of the dough. WRAP the dough ball in plastic cling wrap.
PLACE the wrapped dough ball in your refrigerator for at least 30 minutes. While the dough is resting in your refrigerator, grab a medium-sized bowl.
ADD in ricotta, mascarpone and freshly (finely) chopped thyme. Mix to combine all of the ingredients. Season with salt and pepper. After 30 minutes the ravioli dough should have settled.
UNWRAP the dough and cut it into quarters. Repeat the following steps for each quarter. FLATTEN the dough slightly using the rolling pin. RUN the dough through the pasta maker.
Start with the thickest setting, and work your way up until the dough is thin enough that you can see your hands through it. Usually, this is setting 5 on the pasta maker. Repeat for each dough quarter.
SPRINKLE flour on your clean kitchen top. Layout the thin pasta strips on the floured working area.
SCOOP the cheese mixture you've made before by a teaspoon full near the bottom of the dough.
Fold the dough over and press to seal. Use your fingers to (carefully) remove any air around the sealed cheese mixture.
Use the pastry cutter to cut the ravioli into even squares. Transfer each ravioli square onto a rimmed baking sheet which should be lightly dusted with flour.
FILL a large pot with water and bring to a boil. COOK the freshly made ravioli for about 2 to 3 minutes, until done. The main thing with fresh pasta is that you don't have to cook it for very long until it's done.
For that matter, it's important to keep an eye on it while cooking the pasta. You can also see if the ravioli is done when it floats to the top.
