Hawaiian Sweet Rolls

These are wonderful little nuggets of delicious! They're more like a (slightly sweeter than usual) dinner roll than a "sweet" roll though. Definitely very tasty either way.

Hawaiian Sweet Rolls
From Cook's Country June/July 2015
1 c. pineapple juice
1/2 c. whole milk
6 Tbsp. unsalted butter, divided
1/3 c. honey
5 1/2 c. flour
1 Tbsp. rapid-rise yeast
2 1/2 tsp. salt
1 large egg
2 tsp. white vinegar
2 tsp. vanilla extract

1. Combine pineapple juice, milk, 4 Tbsp. butter, and honey and microwave until temperature reaches 110F. (This should take about 1 minute.)
2. In a large bowl, mix 5 c. flour, yeast, and salt.
3. Slowly stir in pineapple juice mixture.
4. Combine egg, vinegar, and vanilla and then stir into flour mixture.
5. Flour your hands and the counter with remaining 1/2 c. of flour. Kneed dough until smooth and elastic.
6. Turn into greased bowl. Cover with plastic wrap and let rise for 1 to 1 1/2 hours.
7. Punch down the dough. (Actually, I learned that it's better if you gently press it down, but punching is more fun!)
8. Divide dough into 18 equal portions and form into smooth, tight balls. (The Cook's Country folks described a method of dividing the dough into thirds, shaping each third into a rectangle and then cutting each of those into six equal portions. The small rectangles/logs could then be shaped into balls. I tried this method, but still found it difficult to get even rolls. They were still delicious, just really uneven.)
9. Place the rolls into a greased 9"x13" baking dish as they are formed, creating 3 rows of 6. (Or six rows of three, if you prefer.)
10. Cover with plastic wrap and let rise for an additional 1 to 1 1/2 hours. (Or do as I did and let them rise in the fridge overnight.)
11. Remove plastic wrap and bake at 375F for 20-25 minutes. (Add an extra five minutes or so if the dough has been chilled. Mine looked done on the outside, but were still a bit doughy in the centre.)
12. Allow to cool for 10 minutes, then use a spatula/lifter to transfer them to a wire rack. Brush with remaining butter.
13. Serve warm. If you need to reheat them, wrap in tin foil and heat at 350F until warmed through.
