Heavily grease and flour one tube cake pan, a bundt pan will do. Preheat oven to 325.
Mix all dry ingredients with a whisk. Chop the strawberries and place in the measuring cup up to the 2 cup level with 1/2 cup of the sugar in the recipe along with the balsamic vinegar. Stir well and allow to stand while finishing the batter.
To the dry ingredients add the vanilla, the eggs, the oil and mix well. Will be sort of crumbly. With the mixer add the can of drained crushed pineapple. Then add in the strawberry mixture and continue to use the mixer until all is well mixed. Lastly stir in the pecan pieces.
Pour the batter into the cake pan. Place in the oven on a baking sheet to prevent melted shortening from falling onto the oven floor. Bake at 325 degrees for 1 and 1/2 hours or until tests done. Allow to cool in the pan about 20 minutes before removal.
Place the powered sugar in a screen strainer and dust the top of the cake until desired amount is reached.
Better to wait until cake is completely cooled to slice. Very moist!
