1 (6 oz.) orange Jell-o2 cups boiling water
1 cup mandarin orange and pineapple juice, reserved from the canned fruit
1 (6 oz) frozen orange juice concentrate
1 (3.4 oz) lemon pudding mix
1 (8 oz) carton of whipped topping
1 (20 oz)can pineapple tidbits, drained reserving juice (I don't use the pineapple, just the juice)
1 small can mandarin orange (I think these are like 8 or 10 oz), drained reserving juice
Mix boiling water and jello together for 2 minutes. Mix in frozen orange juice concentrate until dissolved. Mix in reserved 1 cup mandarin orange and pineapple juice. Add fruit. (If you don't include the pineapple like I do, you can use 2 cans of mandarin oranges so there are more oranges. I prefer to just use the pineapple in something else & take the juice and only use 1 can of oranges. I've never had any complaints.)
Put in a 9 x 13 dish and refrigerate until set. So that the oranges are well distributed throughout the salad, I carefully take a spoon and arrange the oranges in the pan. I usually do this while it is sitting in the fridge. Otherwise, when you move it from the counter to the fridge, all your "hard work" is out the window. ;)
Make pudding according to package directions. Pour over set jello and refrigerate for 5 min.
Drop whipped topping in several mounds on top of pudding layer and carefully spread. Look at those beautiful layers!
Note: I usually make this a day ahead. However, I do the jello part the night before and let it set up overnight. I also make the pudding and put it in a bowl. The morning of, I just take a paper towel and dab any water droplets from the jello if there is any. Then, just before I take it, I put all the layers together. It has seemed to be the most smooth process for transport and freshness.
