A vacuum raising apparatus for the production of an expanded foodstuff comprises a fluid permeable mould <B>10</B> for constraining the foodstuff <B>22</B>. The permeability of the mould <B>10</B> is substantially uniform throughout so that during vacuum raising, fluids from the foodstuff can escape uniformly through the entirety of the mould <B>10</B>. The mould <B>10</B> may comprise two separable portions. The vacuum raising apparatus may comprise a sheet of alternating flats <B>14</B> and troughs <B>12</B>. Also disclosed is a method of vacuum raising a foodstuff comprising forming first and second edible components, the second component being a fat liquid at body temperature and a protein, co-extruding the first component around the second component, constraining the extruded product within a mould as described and heating the extruded product within the mould under vacuum. |
