A light, crispy cracker texture with three separate layers. The centre dough is coloured.
Dimensions: 47 x 47mm
Appearance: Evenly blistered
Colour: Pale creamy
Texture: Light and crispy
Flavour: Added flavours
Recipe (1) is an enzyme cracker suitable for sheeting.
Recipe (2) is fermented for 18 hours and should be laminated (see forming with a cut sheet laminator below).
|Invert syrup 70%||3.000||-|
|Malt extract 80%||2.000||1.000|
|Acid calcium phosphate||1.100||-|
|Cream of tartar||-||0.620|
|Liquid whole egg||7.570|
The inner dough uses the same recipe, but has added colour. Some suitable food colour additives are:
|B – carotene||orange||E160a|
An "all in" mix on a horizontal mixer
Temperature of about 33oC for enzyme doughs
Two doughs are required of similar consistency, but contrasting colour
The dough is sheeted, gauged and cut, (laminating is not required for recipe (1).
Three dough sheets are required. Each sheeter to produce a sheet of minimum thickness (not exceeding 10mm)
Gauge roll 1: 15.0
Gauge roll 2: 8.0
Gauge roll 3: 4.0
Gauge roll 4: 2.0
The process is not ideal as the 3 sheets will produce a combined thickness of around 30mm. Three gauge roll units are not sufficient to reduce this dough sheet to the cutting thickness of 2.0mm without excessive reductions. This will reduce the spring and open texture of the cracker. An alternative forming method, which is now favoured is described below.
Three layer crackers may be laminated on a cut sheet laminator. The hopper is divided into 3 sections. The two outside sections contain the outer dough and the centre section contains the inner dough. A single dough sheet is produced by the 3 roll sheeter with the outer and inner doughs. The cut sheets are laid so that the inner dough is covered at the top and bottom by the outer dough. The laminated dough is fed to the cutting machine at right angles.

The resulting laminated sheet is gauged and cut in the same way as other cracker doughs. This system gives a good cracker texture and appearance with the contrasting colour in the centre.
Baking time 5.0 mins.
Temperatures: 220 / 220 / 210 / 180oC
High bottom heat in Zones 1 and 2 is required
Baking band: Z47 wire-mesh band. Pre-heat is required
