The late Queen was renowned for her love of quintessentially British foods, as she cherished her afternoon tea spread of scones, finger sandwiches and biscuits - all washed down with a piping hot cup of Earl Grey tea.
The longest reigning monarch also loved utilising the delicious local produce that she had access to at her royal estates in Norfolk and Balmoral, with one of her favourites being freshly caught salmon from the River Dee in Aberdeenshire.
If there's one culinary delight that she took incredibly seriously, it was the humble sandwich, as the Queen thoroughly enjoyed a jam butty and even taste tested her Royal Guard's lunches to ensure they were up to scratch.

The late monarch relished her secret culinary role at her beloved Balmoral estate in Scotland, where she treated her taste buds to a sample sandwich or two before they were delivered to her bodyguards.
One of the Queen 's former Royal Guards, John Ross, spoke of the Queen's penchant for food tasting ahead of her 90th birthday in 2016.
A former soldier in the King's Own Scottish Borders regiment, Ross detailed the Queen's keen interest in making sure her staff's food was of the highest standard before they accompanied her on fishing trips.
He told The Telegraph : "One of Her Majesty's priorities was looking after the welfare of the soldiers responsible for providing support for all events.
"She often tasted our packed lunches to check we were being properly looked after before we went out on hunting or fishing trips. She would come to the kitchen and inspect the sandwiches.
"Most were up to scratch but if they weren't, they'd be sent back."
The ex-warrant officer helped protect the late monarch at Balmoral for 25 years, and praised the late Queen's kindness when looking after her servants.
Throughout history, kings and queens have relied on the assistance of culinary testers to prevent them from being harmed or even poisoned through food.
This tradition is less common for the modern monarchy, as there are plenty of other ways to vet a chef's food preparation.
However, rumours did circulate over the Queen having a personal food taster during her reign, as one Irish chef claimed that someone tested a meal he'd prepared before the late monarch tucked in.
According to People, chef Kevin Dundon cooked a cooked salmon and a roast rack of lamb for the Queen to enjoy - but he claimed that the monarch arranged for a man to taste-test the food before she ate it.
"I produced two plates: One for him and one for her, and he tasted [the meal] before it was served to her," Dundon said.
The royal family's former chef, Darren McGrady, has previously disputed Dundon's claim and insisted that the Queen never had a 'royal taster'.
It may have transpired that the late monarch requested her food be sampled if it was cooked by someone new, as McGrady was a trusted member of royal staff who had a good relationship with the Queen.
McGrady also revealed that the late monarch loved eating jam sandwiches everyday, a staple she charmingly called "jam pennies".
According to her former personal chef, jam sarnies were a staple in her diet for many years, and they simply consisted of bread, jam and butter, staying true to its classically British feel.
On the subject of lunches, many royal fans now associate the beloved Queen with marmalade sandwiches after her heartwarming sketch with children's fictional character Paddington Bear.
The viral skit famously showed the late monarch pulling out a sandwich from her handbag to show Paddington, and the scene has since been recreated in tear-jerking tributes since the Queen's passing.
So many people were leaving marmalade sandwiches 'from Paddington' at the gates of royal landmarks over the weekend, that officials were forced to advise people against bringing a sandwich as part of their tributes.
The original Paddington-themed tribute that left people in tears was a humble sarnie inside a plastic wrapper, with the words 'For later!' scribbled on the front in black pen - echoing what the Paddington would say to the late monarch.
