Red Apron's Toasted Marshmallow Soft Serve
A swirl of the Toasted Marshmallow soft serve topped with chocolate cookie crumbs for a necessary crunch.
Combining Milk and Half and Half
The base of the soft serve is a combination of milk and half and half. MacIsaac explains why she doesn't use heavier creams: "You want to introduce fats/solids to have a creamy mouth feel (milk is about 80% water which makes for an icy soft serve) but I found that when I use heavy cream, the base would start to get too thick as it churned, essentially slowly turning the ice cream into butter."
Add the sugar and heat to a simmer.
Now the Fun Part
Take 3/4 of the marshmallows from the recipe and place on the skewers.
Use a blowtorch or whatever fire you've got to char the marshmallows until really dark. Allow them to catch on fire for a minute or so.
Blow out and use a fork to scrape off the skewer into the hot milk.
Use an immersion blender to blend smooth.
After adding corn syrup and vanilla extract, strain into a large container and chill overnight.
Once the mixture has been chilled, place in to a soft serve machine for serving.
