The Queen was on "sparkling" form as she laughed and joked at a celebratory reception on the eve of her Platinum Jubilee.
The monarch, just hours away from becoming the first British sovereign to reach a historic 70 years on the throne, joined members of the local community in the ballroom of Sandringham House to mark her milestone.
Yvonne Browne, vice-president and chairman of the Sandringham WI, described the Queen as being on "sparkling" form.
The event was the largest in-person public engagement the Queen had attended since before her recent health scare in mid October.
The 95-year-old head of state arrived at the event with a wooden walking stick she rested on sagely as she leant forward to chat to the visitors.
The guests were seated around tables waiting for a tea to be served but stood up respectfully to chat to the Queen.
Wearing an Angela Kelly wedgwood blue crepe with white brocade dress, the Queen, who beamed with delight throughout, also carried her trademark black handbag.
She cut a cake decorated with the Jubilee emblem to begin her Platinum year.
Among the guests were members of the Sandringham branch of the Women's Institute, Sandringham Estate pensioners and representatives from two local charities West Norfolk Befriending and Little Discoverers.
The Queen also met former cookery school student Angela Wood who helped to perfect the famous dish coronation chicken served to guests after the Queen's 1953 Coronation ceremony.
Mrs Wood made the Queen laugh when she told the monarch she spent "days and days altering it for Constance Spry and Rosemary Hume".
Commenting on how the recipe for coronation chicken has likely developed over the years the Queen told Angela Wood: "It's probably changed because in those days we did some things quite differently."
Shaun Mason, a junior sous chef, had created tiny bite size morsels of the coronation chicken, chicken with curry spices, apricot in a savoury tartlet, and he carried a tray of his creations into the ballroom and announced they were available to sample.
As the morsels were placed between the Queen and Mrs Wood to try, the room erupted with laughter when the Queen quipped "I'll go away", she turned to add: "You can tell me (what you think) when I come back."
On October 19, the Queen held a Windsor Castle evening reception for delegates for the Global Investment Summit.
But the next day she cancelled a two day trip to Northern Ireland, was secretly admitted to hospital for preliminary tests, before being put under doctors' orders to rest and only carry out light duties.
Before the pandemic the Queen would visit her WI colleagues at West Newton village hall every year as part of her winter stay on her Sandringham estate in Norfolk.
The Queen's Platinum Jubilee will be celebrated across the country during an extended June Bank Holiday in honour of a monarch who has left an indelible mark on the life of the nation.
But February 6, the date of the Queen's accession to the throne, is a poignant period for the Queen, as it is the day her father King George VI died in 1952.
She is already the nation's longest reigning monarch, and the longest still-serving sovereign in the world.
During the reception the Queen also met representatives from West Norfolk Befriending a charity which aims to reduce the social isolation experienced by the elderly by matching them with trained volunteer befrienders who visit on a regular basis.
And she spoke to members of Little Discoverers which provides early education for pre-school children with movement difficulties and delayed development.
When the Queen was presented with a copy of a "Loyal Address" written by primary schoolchildren from West Norfolk the head of state gave a frank opinion on public proclamations she has heard during her long reign.
The Queen seemed to approve of the words from the younger generation who said about the Queen: "You have shown a caring manner, determination, and dedication to help other people. We think you're doing a great job! We are very lucky to have had you as our Queen for so long.
"We are proud of you for helping us through this pandemic with your inspirational words, and by your actions setting a good example, especially as the last year has been so hard for you."
After reading the address, on display in the ballroom, the Queen said to laughter from the guests: "Most addresses are usually pompous...this is so much nicer."
The afternoon reception which the Queen clearly enjoyed ended with the cutting of an iced Victoria Sponge with the Platinum Jubilee logo as its decoration.
Lady Dannatt, the Lord-Lieutenant of Norfolk, told the Queen the cake was turned upside for the benefit of the press photographs and the quipped to laughter "I don't matter?"
When it came to cutting the large cake the Queen thinking aloud said: "I'll put the knife in, see if it works" and she drove the knife in vertically and left it place adding "somebody else can finish it off".
