When French fries are removed from the oil bath, oil uptake occurs due to capillary action (Bouchon, Aguilera, & Pyle, 2001) and due to a sudden pressure drop in the pores as a result of steam condensation (Gamble, Rice, & Selman, 1987). The porosity of the crust and the size of the pores co-determine how much oil is taken up.
