Salty Peanut Protein Bar

Headnote

This bar is built for clarity of flavor and disciplined texture: a dense milk-protein core, a clean peanut line, and a restrained salt finish. The structure is firm yet yielding, with enough richness to feel complete and enough sweetness to remain composed. It is a modern confection, but one made with the precision of a patisserie.

Ingredients

Protein base

18 g milk protein

6 g collagen hydrolysate

8 g polydextrose

4 g sweetener

2 g salt

Fat and binder

6 g cocoa butter

4 g palm kernel oil

3 g glycerol

2 g emulsifier

Peanut component

2 g peanut butter

0.5 g peanuts, finely chopped

Method

1. Set the mold on a stable tray. Combine the milk protein, collagen hydrolysate, polydextrose, sweetener, and salt in a small bowl. Whisk thoroughly until the mixture is perfectly even and free of visible streaks.

2. Place the cocoa butter and palm kernel oil in a small saucepan over very low heat. Warm just until fully melted and clear, 2 to 3 minutes. Remove from the heat and stir in the glycerol and emulsifier until smooth and unified.

3. Add the melted fat mixture to the dry ingredients in two additions, stirring after each addition with a silicone spatula. The mass should become thick, cohesive, and slightly glossy. Fold in the peanut butter and chopped peanuts and mix only until evenly distributed.

4. Press the mixture firmly into the mold in one continuous layer, compacting it with the back of the spatula so there are no voids. The surface should be level and taut.

5. Chill for 10 to 12 minutes, just until set enough to unmold cleanly. The bar should feel firm to the touch, with a dense, sliceable interior and no tackiness on the surface.

Plating and serving

Unmold the bar and serve it whole, centered on a plain plate or wrapped with precision for service. The finish should be clean and matte, with the peanut flecks visible only as a quiet signal of flavor.

Professional notes

The dry mix must be fully homogeneous before the fats are added; any inconsistency will show in the final bite.

Melt the fats gently. Excess heat will dull the texture and flatten the finish.

Compression in the mold is essential: this is what gives the bar its clean fracture and compact chew.
