=No. 2 Neutral Lard.=--This is a neutral lard made from back fat. At
times it is profitable to make this product into No. 2 neutral instead
of steam lard, for when the market for No. 1 neutral is extremely high
there is demand for a good No. 2. When making this, the rind should
be skinned off from the back fat, leaving clear back fat to be hashed
for neutral. If the rinds are put in, it gives the product a “hoggy”
flavor, which makes it undesirable. It is hashed and melted the same
as No. 1 neutral, except as to temperature, the melting point for this
being 132° to 134° F., method and apparatus as described for the making
of No. 1 neutral, being applicable to this.
_Test--Pure Steam Lard vs. Neutral._--Below is a test on raw leaf lard
rendered into neutral, showing yield, and percentage of the neutral
lard produced; the scrap and bottoms from the kettle being run into
kettle rendered lard.
