Preheat oven to 400 degrees. Combine pretzels with melted butter and 1 T sugar. Spread in bottom of 9x13" pan. Bake 8-10 minutes. Cool to room temp.
Blend softened cream cheese and 3/4 C sugar. Fold in Cool Whip (or fresh whipped cream). Spread this mixture on the COOLED pretzel crust.
Dissolve Jell-O in boiling pineapple juice. Stir in frozen strawberries. When partially set, pour over cream cheese layer and refrigerate until completely set (at least 3 hours).
This Strawberry Pretzel Salad is another goodie from Mom/Mimi's recipe treasury. Personally, I thought it was a wee bit too sweet, so I reduced the sugar. Also, the originally recipe called for boiling water, but we use pineapple juice. It adds flavor!
Fresh Whipped Cream may not be as "stable" a texture as Cool Whip. BUT it isn't so processed. You decide. It's going on your table.
