Every lunchtime, DailyEdge.ie rounds up the TV shows that you’ll be tweeting about tonight and talking about tomorrow.

Black Mirror: White Christmas (Channel 4, 9pm)

Jon Hamm (Mad Men) stars in Black Mirror’s unlikely ‘Christmas special’, penned once more by Charlie Brooker. The 90-minute show contains three darkly satirical mini-stories – one of which will focus on ‘blocking’ people in real life as you would on social media. Wonderfully creepy. #blackmirror

The Great British Bake Off Christmas Masterclass (BBC2, 8pm)

Get out the notebooks and pens – you’re going to need these recipes next week. Paul Hollywood and Mary Berry divulge how to make perfect mince pies, Christmas puddings, and fruitcakes, as well as some other tasty treats. #gbbomasterclass

Bressie’s Teenage Kicks (RTÉ2, 10pm)

Over the series, Bressie has formed a band with five teenagers from different communities in Limerick. The final episode sees his young charges record their first EP and play a major gig in Limerick, after six months of writing and rehearsing. Will they make him proud? #teenagekicks

Everyone’s talking about: #Sherlock

BBC BBC

It may have been nearly a year ago, but Sherlock’s return from the dead in Season 3 of the hit BBC series has been named as 2014′s most shocking TV moment – the Independent reports that there were over 639,000 tweets about the first episode alone.

Unsurprisingly, Oberyn Martell’s extremely gory death in Game of Thrones came second. We won’t be reliving that any time soon.

Or switch over for…

• Harry Potter and the Order of the Phoenix (UTV, 7.30pm) Voldemort is back, Harry is stroppy, and a new professor shakes up Hogwarts for the worse.
• The Supervet: Christmas in the Clinic (Channel 4, 8pm) Noel Fitzpatrick treats a Labrador in need of a hip replacement. Get the tissues :’)
• Homeland (RTÉ2, 9pm) The penultimate episode of the US spy drama.
• Tommy Tiernan – Crooked Man (TV3, 10pm) The comedian performs a live set in Cork.
• Grey Matters (RTÉ One, 10.15pm) Documentary about Irish designer and architect Eileen Grey.
