Hi Nammu. I have never made Peppermint Divinity, and though I've made meringue cookies, the procedures/methods were a bit different. I looked online and most all Peppermint Divinity recipes seem to have the same base ingredients and method. I think that if you read the instructions a few times, it may seem less intimidating. All you really need are the right tools (the basics, something to beat the eggs into peaks, and a candy thermometer) as well as the ingredients. Of the ones I saw, the only less common ones might be corn syrup, candy canes (if your mother incorporated them), and perhaps food coloring, if she deliberately colored the meringues red/pink and green. The boiling to hard-ball stage is really not difficult at all, if you have the candy thermometer (or meat thermometer that goes to high temps) and watch the temperature attentively. The drizzling step wouldn't be hard.

Did your mother's Peppermint Divinity include actual candy canes? If not, if they tasted like them she might have used peppermint extract. In such a case, only a small amount of extract would be needed. The recipe at Peppermint Divinity Recipe | Southern Living | MyRecipes actually flavors the meringues peppermint with only candy canes, and includes a nice decoration with them. They then obviously only have a pink hue, but the pink comes directly from the candy canes (no food coloring). For other colors, using food coloring is not that hard. One drop at a time, until the desired color.

They look yummy! I like peppermint flavor.
