In a large bowl, whisk together 5 1/2 cups flour, sugar, yeast, salt and turmeric (if adding). Set bowl aside.
In a second bowl (preferably a stand mixer bowl if you have one), with the paddle attachment, cream the potato, butter, and vanilla together. Add in 3/4 cup of water and combine.
Add the flour mixture in 3 parts. Blend on low speed using the paddle attachment between the first 2 parts. Remove the paddle and scrape off any excess on the attachment back into the bowl. Switch to dough hook and add the rest of your flour on low speed until all the flour is combined.
Knead in the stand mixer for 15-20 mins or until it doesn't stick to the bowl. It will pull away from the dough. Still slightly sticky but not sticking to your hands. *If dough is dry add additional water 1 tbsp at a time. If too sticky add additional flour 1 tbsp at a time.
Spray bowl, form into a ball and place ball inside. Cover with a towel or plastic wrap and let sit for 60-90 minutes in a warm, draft free place until doubled (may take longer).
Punch it down. Let rise again for 40-60 minutes until doubled in size again (may take longer).
Prep two bread loaf pans with parchment paper and grease with oil. Set aside.
Uncover, punch down again and take out.
For the 3 or 6 bun loafs - For the 3 roll loaf - Cut your dough into 6 even pieces. Use a scale for accurate measurements. Gently flatten a piece, fold left and right sides into the middle, then roll ends into a log. Place 3 pieces in each of your bread pans next to each other. For the 6 roll loaf - Cut your dough into 12 even pieces. Use a scale for accurate measurements. Grab a piece and fold the ends under shaping into a ball. Then roll the dough into a ball with the ends at the bottom. Make 2 uneven rows of 3 balls. Cover for 35-40 to rise again.*If you push the dough and it springs back it's not ready. If it doesn't spring back at all or very slowly it's ready.
15 minutes before done, preheat oven to 375 degrees F. Make the simple syrup by adding the maple syrup and melted vegan butter to a bowl and whisk.
Once ready, brush the dough with the simple syrup mixture.
Bake for 35-40 minutes or under golden brown on top. Remove from oven and serve.
