Rising avocado prices in Mexico caused by poor harvests and cartel control have reportedly prompted taco chefs to substitute them for courgettes in guacamole, the staple dip on the table of nearly every restaurant in Mexico.
Avocado prices in Mexico have soared in recent months due to a poor crop, forcing enterprising chefs to swap them for cheap and plentiful courgettes in the dip - and successfully fooling customers in the process.
Rising demand for the fruit in the US, caused by the craze for brunch dishes such as avocado on toast, as well as a weak crop in California, is increasing demand and forcing prices up in Mexico.
Last week, the price of Hass avocados from the violent southern state of Michoacán, the heartland of Mexico's production, jumped some 7 per cent to a record-breaking 650 pesos (£27) for 10 kilograms, according to government data reported by Bloomberg.
