Meghan Markle and Prince Harry's Thanksgiving preparations have been revealed.

In the latest newsletter for her lifestyle brand As Ever, the 43 year old Duchess of Sussex gave supporters an update on her upcoming holiday season with her 40 year old husband and their children - son Archie, six, and daughter Lilibet, four.

She and her family are preparing for Thanksgiving at their $30 million Montecito, California home by harvesting sage from their garden.

They'll use the herb to season their homemade feast.

Sage is one of Markle's "favourite" flavours, according to the newsletter (per the Daily Mail), reports the Express US.

She has been documenting "flowering sage" in her backyard on Instagram over the last year.

"Those photos you've seen this year on our Instagram of Meghan walking through what seems like lavender, with its gorgeous purple hue, actually share the beauty of flowering sage (Fun fact: the varietal is called Santa Barbara)," the newsletter said.

However, this has not been a solo project of Markle's, as the newsletter revealed that the entire family has been involved in the harvest.

She recalled "strolls" through the garden with Harry, Archie, Lilibet, and their two dogs and how growing sage was a part of their family's "sun-drenched moments" together. "Those strolls, with Archie and Lili running in tow, her husband checking on the bees, Pula chasing the ball with Mia trying to keep up - those were the sun-drenched moments that made an everyday walk something a bit more magical," the newsletter revealed.

It continued, "And that sage, that purple, that scent around the garden, was always there in the background."

However, Markle isn't simply reflecting on treasured family moments.

She's simultaneously marketing As Ever's latest Sage Honey with Honeycomb, priced at $32.00 for a 9 oz. jar on the company's website.

The newsletter explained that Markle drew inspiration to create the product after incorporating her home-grown sage into honey harvested from her own backyard beehives.

This homemade sage honey rapidly became a household "treat" and even a cherished gift for friends.

"Here we are: a stunning sage honey, aromatic and earthy, epicurean in its depth of flavor and elegant simplicity, inspired by the treats she enjoys at her home with her family," As Ever's newsletter stated.

"Our Sage Honey is now available for your holiday table, to beautifully dress your Thanksgiving feast-either on the bird or on the vegetables. Or in a vinaigrette. Or as a spoonful in your tea. This special honey is the top holiday tip you'll want to share. Enjoy!".

Customers purchasing Markle's honey receive additional guidance on utilising it to craft their own "Montecito Thanksgiving love story."

Blending As Ever's Sage Honey with Dijon mustard, lemon juice, assorted spices, and cooking stock creates Markle's mouth-watering As Ever Sage Honey Glaze.

"When dreaming up the Holiday Collection months ago, Meghan imagined what it would taste like to have a sage honey drizzled on her Thanksgiving turkey," the newsletter revealed about the former royal's concept.

The official As Ever Instagram profile also posted footage of Markle appearing stunning in a burgundy dress whilst glazing a succulent turkey at her family's dining table.

The footage additionally displayed Markle crafting an sophisticated tablescape, featuring cloth serviettes tied with green velvet ribbons that were positioned on porcelain plates.

The post, published Tuesday, November 18, was captioned, "Our table is set with a seat just for you."

Last November, Markle revealed to Marie Claire that her and Prince Harry's Thanksgivings are "always pretty low-key.

"I think you always make sure there's room at the table for your friends who don't have family, which is really key," she disclosed at the time.

Nevertheless, Markle emphasised that Archie and Lilibet remain her top priority, and that the festivities have become more delightful as they've matured.

"We're always making sure we have something fun to do. At first, I think as a mom with children you're just enjoying having them there, but they're not understanding everything that's happening yet," she clarified. "But now we're at the age where I just can't wait to see it through their lens every year."
