Cut butcher's twine into 30-34 inch pieces, and set aside.
Set up a workstation with the banana leaves, butcher's twine, pasteles paper, achiote oil, masa, veggies, red pimentos, olives, and filling.
Place one sheet of pastel paper or parchment paper in front of you. Then place a banana leaf on top of the paper towards the edge close to you.
Brush a little bit of achiote oil onto the center of the banana leaf.
Scoop 1/2 cup of the masa onto the banana leaf and spread out into a rectangle.
Spread 1/4 cup of filling down the center, and add red pimentos and olives on top if you like.
Fold the masa in half using the banana leaf. Pull the banana leaf back towards the edge of the parchment paper and roll the parchment paper over the banana leaf once.
Then press down the edges of the banana leaf pushing the masa toward the center of the pastel and fold in the sides of the parchment paper on both sides.
Once the sides are folded in, keep rolling your pastel forward, flattening it out as you go. Set aside the pastel and repeat the process to make another pastel. Use the same technique and watch the tutorial for more details. It takes time to practice.
After rolling another pastel, you can tie them together or individually. Tie one pastel or two together like a present. I recommend you watch the tutorial to see the process.
You can boil them right away or freeze them for later. If you are boiling them right away, add a dash of salt to the water and boil for 30 minutes. If you are boiling them frozen, add salt to the water and boil them for 60 minutes.
Once they are cooked, turn off the stove and let them sit for 10 minutes. Then carefully using a pair of tongs, pick the pastel out of the water by the string and place it on a plate or tray. Cut the string, carefully unwrap it, and enjoy.
