Infusion kit and tools and method for using same

A system comprising:

• a permeable container configured to contain an additive substance, said permeable container having a first lid portion configured to seal an opening of said permeable container, said first lid portion comprising a main portion having a top planar side and a bottom extension opposite said top planar side, wherein said bottom extension is sized to extend into said permeable container, and said first lid portion having a lip extending around a perimeter of said main portion, said lip being perpendicular to a plane of said top planar side, wherein said lip is sized to fit around an opening edge of said permeable container, and wherein said lip and said bottom extension define a first recess therebetween, said first recess being sized to retain said opening edge of said permeable container;
• a non-permeable container configured to contain both said permeable container and a base substance, wherein, when said permeable container is inside said nonpermeable container, a space is formed between an outer wall of said permeable container and an inner wall of said non-permeable container, and wherein said permeable container is immersed in said base substance when said permeable container is inside said nonpermeable container;
• a heat-tolerant casing separate from the non-permeable container, said heat-tolerant casing being configured to removably fit around said permeable container, wherein, when said heat-tolerant casing is fitted around said permeable container, a gap is formed between said outer wall of said permeable container and an inner wall of said heat-tolerant casing, said gap being of a size sufficient to permit insertion and removal of said permeable container from said heat-tolerant casing and to permit a desired temperature control during a roasting process, and wherein said heat-tolerant casing is non-permeable;
• and
• a non-permeable lid portion configured to seal an opening of said non-permeable container, said non-permeable lid portion comprising a lid base, an outer flange extending around a perimeter of said lid base, said outer flange being perpendicular to a plane of said lid base, and an inner flange extending from the lid base, said outer flange and said inner flange defining a second recess therebetween, said second recess sized to retain an edge of said opening of said non-permeable container, and said inner flange defining an interior recess of said non-permeable lid portion,
• wherein said first lid portion is sized to nest within said interior recess such that an entire surface area of said top planar side of said first lid portion fits within said interior recess,
• wherein said non-permeable lid portion and said non-permeable container are made of silicone,
• wherein a seal formed by said non-permeable lid portion with said non-permeable container is air-tight and water-tight,
• wherein said permeable container, said non-permeable container, and said non-permeable lid portion are heat-tolerant,
• wherein said base substance is infused with said additive substance by heating said non-permeable container to a predetermined infusion temperature for a predetermined infusion time,
• wherein said permeable container, said non-permeable container, and said non-permeable lid portion form an infusion kit for infusing said base substance with said additive substance,
• wherein said first lid portion is configured to cooperate with and nest within said non-permeable lid portion,
• and wherein said non-permeable container and said non-permeable lid portion are configured to be immersed in a heated liquid bath.
