1-First Step: Gather and prep your tools Set out a large mixing bowl, a whisk or spoon, and your mold or serving dish. If you are using a decorative mold, lightly rinse it with cool water, then drain it well. This can help the finished dessert release more easily later.

2-Second Step: Dissolve the gelatin Pour the 2 cups boiling water into the bowl with the 6-ounce package strawberry gelatin. Stir for about 2 minutes, or until the gelatin is fully dissolved and no grains remain. This part matters because undissolved gelatin can leave little gritty bits in the finished mold.

3-Third Step: Add the cold water Stir in the 1 cup ice-cold water. Mix well so the gelatin starts cooling down. The mixture should still be liquid, but it should not be steaming hot when you move to the next step.

4-Fourth Step: Fold in the cranberry sauce Add the 15-ounce can jellied cranberry sauce to the bowl. Whisk or stir until the cranberry sauce breaks down and blends into the gelatin mixture. You may still see a few small pieces, and that is fine. They add a nice homemade look.

5-Fifth Step: Mix in the sour cream Stir in the 1 cup sour cream. Mix until the color turns pale pink and the texture looks creamy and smooth. If you want a more even look, whisk a little longer to help the sour cream blend fully.

6-Sixth Step: Pour into the mold Carefully pour the mixture into your prepared mold or dish. Tap the bowl gently on the counter once or twice to release any air bubbles. If you are using a large mold, make sure the mixture is spread evenly so it sets at the same rate.

7-Seventh Step: Chill until firm Place the mold in the refrigerator and chill for at least 4 to 6 hours, or until fully set. For the best results, let it chill overnight. A well-set mold will feel firm to the touch and hold its shape cleanly when unmolded.

8-Final Step: Unmold and serve To unmold, dip the bottom of the mold briefly in warm water for just a few seconds. Do not soak it too long, or the edges may melt. Gently loosen the sides with a knife if needed, then invert onto a serving plate. Add whipped cream for serving, optional, if you want a soft, sweet topping.
