Pumpkin Spice Caviar Spheres with Crispy Sage & Maple Foam

Components:

1. Pumpkin Spice Base for Spherification
2. Calcium Lactate Bath for reverse spherification
3. Maple Foam using soy lecithin
4. Crispy Sage Chips

Equipment Needed:

• Precision scale
• Blender or immersion blender
• Fine mesh strainer
• Small caviar syringe or pipette
• Slotted spoon
• pH test strips (ideal range: 4.0–4.5 for spherification)
• Immersion circulator (optional, for foam)
• Non-stick skillet

Step-by-Step Instructions

1. Pumpkin Spice Liquid for Spherification

This will be encapsulated into caviar-sized pearls.

Ingredients:

• Pumpkin purée – 60g (¼ cup)
• Apple cider – 120g (½ cup)
• Maple syrup – 10g (2 tsp)
• Ground cinnamon – 1g (½ tsp)
• Ground nutmeg – 0.5g (¼ tsp)
• Ground clove – 0.25g (⅛ tsp)
• Calcium lactate – 4g (approx. 2 tsp)
• Filtered water – as needed to thin (aim for a smooth, pourable liquid)

Instructions:

1. Blend all ingredients until smooth. Strain through a fine mesh sieve.
2. Check pH. If below 4.0, raise it using a small pinch of sodium citrate. Ideal pH is 4.2–4.5.
3. Refrigerate while preparing the sodium alginate bath.

2. Sodium Alginate Bath (for Reverse Spherification)

Ingredients:

• Filtered water – 500g (2 cups)
• Sodium alginate – 2.5g (approx. 1¼ tsp)

Instructions:

1. Using a blender, combine water and sodium alginate. Blend thoroughly to avoid clumping.
2. Let sit for at least 30 minutes to eliminate air bubbles.
3. Pour into a wide bowl for spherification.

3. Create Pumpkin Spice Caviar Spheres

Instructions:

1. Fill a pipette or syringe with the chilled pumpkin spice mixture.
2. Drop small droplets into the sodium alginate bath, spacing them to avoid clumping.
3. Let each sphere sit for about 1 minute.
4. Gently remove with a slotted spoon and rinse in a clean bowl of water.

4. Maple Foam (Lecithin-Based)

Ingredients:

• Maple syrup – 40g (2 tbsp)
• Filtered water – 80g (⅓ cup)
• Soy lecithin – 1.5g (approx. ½ tsp)

Instructions:

1. Blend water, maple syrup, and lecithin using an immersion blender until frothy.
2. Allow foam to stabilize for a minute. Skim foam off the top gently with a spoon or siphon into a serving vessel.
3. (Optional: Keep warm using a water bath at 50°C/122°F.)

5. Crispy Sage Chips

Ingredients:

• Fresh sage leaves – 10–12
• Neutral oil (e.g. grapeseed) – for frying
• Sea salt – to taste

Instructions:

1. Heat a small amount of oil in a skillet over medium heat.
2. Fry sage leaves for 10–15 seconds until crisp. Transfer to a paper towel.
3. Sprinkle with sea salt while warm.

Assembly

1. Place 4–5 crispy sage leaves on each plate.
2. Carefully spoon 1–2 teaspoons of the pumpkin spice caviar pearls onto each leaf.
3. Finish with a dollop or scoop of maple foam on the side or delicately over the spheres.
4. Serve immediately for the best texture and visual impact.

Tips for Success

• Balance your base: Keep the pumpkin spice liquid thin enough to pass through a pipette. If too thick, the spherification won’t form clean spheres.
• Mind your pH: Reverse spherification depends on a precise pH level. Test and adjust before dropping into the alginate bath.
• Serve fresh: Spheres continue to gel if left too long; serve within 15 minutes of creation.
• Practice makes perfect: Test a few drops first to dial in timing and size before creating your final batch.
