The biggest food price rises have been laid bare in new research - with the price of pasta having nearly doubled in two years.
A standard 500g bag of pasta has risen in price by 90% - from 50p to 95p - according to BBC analysis.
The price of strawberry jam has gone up from 73p to £1.15, an increase of 57%, while oven chips are up from £1.24 to £1.80, a rise of 45%.
Overall, the price of a small basket of 15 everyday essentials has shot up by £5.34 - from £15.79 in 2021, to £21.13 in 2023.
The prices were tracked at Asda, Tesco, Morrisons and Sainsbury's by retail research firm Assosia.
Food costs remain one the biggest drivers of inflation, with the rate of food price rises still running at 16.7%.
The rise in the cost of groceries has been accelerated by the war in Ukraine, which pushed up the price of animal feed, fertiliser and vegetable oil.
Kay Staniland, director at Assosia, said: "It's inflation on top of inflation at the moment.”

The latest update on food prices comes after supermarkets started rationing fruits and vegetables following a nationwide shortage.
Asda and Morrisons were the first to bring in restrictions on Tuesday, followed by Aldi and Tesco on Wednesday.
Tesco and Aldi are limiting customers to three of tomatoes, peppers and cucumbers, while Asda is also rationing customers on lettuce, salad bags, broccoli, cauliflower and raspberries, and Morrisons has set a limit of two items per customer across tomatoes, cucumbers, lettuce and peppers.
The shortages are due to cold weather affecting suppliers in Spain and Morocco , which has meant tomatoes are taking longer to grow.
In the UK, higher energy bills mean farmers are using heated greenhouses less - resulting in fewer crops.
