Is this a cocktail or a mocktail?
Either. The recipe is written as a mocktail base with optional add-ins for a cocktail version. If you want it boozy, dark rum, bourbon, or an amaro-style liqueur all work.
Where did the citrus go if there is no lemon juice?
We get the lift from lemon peel or zest steeped in the hot base. Then you strain it all at the end, so the citrus perfumes the drink without adding acidity that can cause curdling with warm dairy.
Can I add lemon juice anyway?
If you are using dairy milk, skip it. Acid plus warm dairy can turn the drink grainy or separated. If you are using a dairy-free milk, some brands handle a little acid just fine, but it varies. Do a micro-test: add a few drops of lemon juice to your glass first, stir, and if it looks smooth, proceed (start tiny and taste as you go).
What makes it “herbal” if it is creamy and nutty?
Rosemary does the heavy lifting, and a tiny pinch of black pepper keeps the sweetness in check. If rosemary is not your thing, thyme is a softer swap.
Can I make it nut-free?
Yes. Swap walnuts for toasted pumpkin seeds (pepitas) or sunflower seeds. Keep the oats for that toasty flavor and body.
Is it gluten-free?
It can be. Use certified gluten-free oats if you need to avoid cross-contact.
Why strain it?
Oats and nuts give up flavor fast, but they also leave grit. Straining gives you a smooth drink with the same roasted, nutty payoff.
What if I do not have a fine-mesh strainer?
Use a regular strainer lined with a clean kitchen towel, coffee filter, or a couple layers of paper towel. Go slow and do not press too aggressively or you can push starch through.
