Palmini noodles are a low-carb noodle substitute made from the heart of palm, sourced from palm trees. They have a very similar taste and texture to traditional wheat noodles. However, they have a very slight acidic aftertaste, but it is easily masked by sauce and is mostly diminished if you thoroughly rinse the noodles. I have also read that you can soak them in your milk of choice for 30 minutes to eliminate the acidity, but I have never tried this.
