Unless the Egyptian currency is linked to the dollar, a weaker dollar wouldn't make their food more expensive.

The Egyptian Pound may or may not be formally linked to the US Dollar, but the exchange rate has been roughly 5.5 EGP per USD, plus-or-minus 5% for the last five years.

The exchange rate has been rising recently, meaning it takes more EGP to buy a USD, making it even more difficult to buy dollars to pay for things that are priced in dollars, whose price in dollars is also increasing.

So the blame for higher prices belongs to the Egyptian Pound, not the US Dollar.
