This infusion is filtered and a solution of gelatine (10 sheets (about 20 g) for 1 liter of water) is

added. A parsley puree, which gives a beautiful green colour to the mixture is added and we start to

whisk the solution in a mixer. Then, we whisk the mixture with hand, on ice.

III.16.7.2. Meeting with Pierre Gagnaire:

According to Pierre Gagnaire, the foam on is too thick, and the quantity of air bubbles is not

enough important. We tried to whisk again the foam but the air bubbles didn’t stay in the solution. We

looked after which factor has an impact on the foam texture.

We tried to set foam without adding some chlorophyll. The foam mass was 169 g and its volume

was 11 x 8 x 4.8 cm = 422.4 ml. This foam had a good texture, but was not satisfactory in colour.

Furthermore, the same solution, whisked by hand gave a better result in terms of texture; lighter and

more foamy, as wanted by the Chef.

Also, we tried to set a foam with some chlorophyll (one tablespoon). The foam mass was 170 g

and its volume was 11 x 8 x 2.3 cm = 202.4 mL. This foam was heavy and contained eight time less air

bubbles than the forme

III.16.7.3. Discussion/ Interpretation:

Is the chlorophyll responsible for heaviness of the foam?

Of what is constituted this chlorophyll? The chlorophyll is a lipid (oil droplets are observed at the

surface)

Are additional proteins added? (from the white stock?)

The chlorophyll is important for the colour of the infusion, but its quatity has to be small in order

not to make the foam fall down.

Is the chlorophyll totally needed? Can’t we infuse the parsley with the other aromatic herbs? Can
