Ingredients

FOR THE DRINK

• 2 shots (60ml) freshly pulled espresso
• 4–6 oz tonic water
• 1 tbsp pure maple syrup
• Ice cubes

FOR THE TOASTED WALNUT FOAM

• 2 tbsp toasted walnuts
• 3 tbsp milk (dairy or plant-based)
• 1 tsp pure maple syrup
• ¼ tsp soy lecithin powder (optional for stability)

Instructions

1. Preheat oven to 350°F (175°C). Spread walnuts on a small baking sheet and toast for 5–7 minutes until fragrant; let cool.
2. Combine toasted walnuts, milk, maple syrup, and soy lecithin in a blender and blend on high for 30 seconds until frothy. Strain through a fine mesh sieve into a chilled bowl and refrigerate foam while you prepare the drink.
3. Brew two shots of espresso and let them cool slightly.
4. Drizzle maple syrup around the inside of a tall glass, then fill with ice cubes.
5. Pour tonic water into the glass, then slowly layer the espresso over the back of a spoon to create a layered effect.
6. Give the walnut foam a quick froth with an immersion blender or milk frother and spoon it generously over the top of the drink.
7. Garnish with a few crushed toasted walnuts or a light dusting of smoked sea salt and serve immediately.

Notes

Note: For best results, use fresh, high-quality espresso beans and chilled tonic water. Foam can be gently beaten again if it begins to collapse.

Tips & Variations

• Vegan swap: Replace dairy milk with oat or almond milk and omit soy lecithin if desired.
• Smoke boost: Stir a pinch of smoked sea salt or smoked paprika into the maple syrup for extra depth.
• Cold brew option: Substitute cold brew concentrate for espresso if you prefer a gentler extraction.
• Storage: Prepare the walnut foam up to 1 day ahead and keep it chilled; re-froth briefly before serving.
• Garnish ideas: Top with finely grated orange zest or a few whole toasted walnut halves for extra flair.
