Later on when I was a teenager she made layered Jello desserts - fancy rainbow colors in tipped wine glasses. She started making cakes of all kinds and even fancier desserts around this time as well as she became an even more accomplished gourmet cook.
One of my favorite desserts in the younger years was coffee jello. My mom saved the percolated leftover coffee in the refrigerator and added gelatin and sugar and chilled them in custard cups or glass dishes. It was so simple and was served with whipped cream - sweetened, I'm sure. We all loved it as I remember.
Lately, I've been making my own homemade coffee jello in glass OUI yogurt containers (they have covers available on Amazon.) They make a great dessert and I've used both no sugar or a packet of Truvia for 3-1/2 cups. I add about 1/2 cup of no-sugar whipped cream and a few drops of no-sugar caramel syrup or some espresso crystals. It's a yummy treat and an after-lunch pick-me-up.
