Warm your pineapple juice in the microwave (so it's very warm, but not hot)
Add it to the bowl of a heavy-duty stand mixer, the pour in sugar and stir.
Sprinkle instant yeast over liquid. Let stand for 10 minutes. Once you see bubbles and foam form, continue to next step.
Attach dough hook to machine then add the oil, eggs, vanilla, ginger and salt. Mix at low speed until ingredients are incorporated.
Add flour, one cup at a time, and knead for 3 minutes.
Lightly spray or grease two 9x13-inch pans or 1 large rimmed cookie sheet.
Turn out dough on a lightly floured surface. Cut off small sections and form into 2-3 inch balls. Place in pan about a half inch apart. Cover and let rise until double in bulk, about 30 minutes.
Preheat oven to 350°F/175°C.
Bake rolls for 20-25 minutes or until golden brown. Broil the last minute to add more golden brown, if desired.
Notes
Warm pineapple juice in microwave for 1-2 minutes until very warm, but not too hot.
If in a pinch, you can use water instead, but your rolls won't be quite as amazing!
