In the holiday season, while there's so much going on which the most energetic individuals may occasionally anticipate a quiet break in January, it's all too easy to overlook things. I believe I cannot be the sole person who has once been startled awake while at work because of an inquiry from someone asking, "What time should we come over later?" Don't worry; whether you're distracted, and simply likely to make impromptu gatherings, I have some solutions.
Firstly, though I can't stress it enough, if you have organized for a year or just a quarter-hour, the greatest events tend to be the easiest. All everyone really wants are a good chat, something to drink, and enough food so guests do not feel like chewing their arm on the bus home. Unless you are Jay Gatsby, no one expects a full bar, Michelin-starred food or a live band.
The best gatherings are the easiest. That said, a theme helps to cover up the fact you have only thrown the event on on the way back from the office.
That said, an overarching idea works well for disguising that you've just put the party together while returning after work. And by theme, I mean for example a seasonal celebration. Getting a bit more specific (Scandinavian Christmas, for instance, with mulled wine, warm beverage, fish snacks plus crispbreads, folk tunes playlist; alternatively Mexican Christmas, including traditional drink, chilled brews or cocktails, along with plenty of snacks, salsa & avocado dip, and Luis Miguel in the background) can narrow your options during the inevitable grocery run.
In the store, select a drink or two (an alcoholic option for those who do, a non-alcoholic one for some prefer not to) and a few appetizers suited to your concept, and get as many as possible, rather than fretting about giving people too much choice. Nothing looks as generous and celebratory than plenty – I would consistently prefer to arrive with a tub stocked with iced containers with competitively priced crémant or cava than a small serving of fancy champagne. (Include several packs for chilling, too; there is never sufficient ice.)
Should you demonstrate skills and offer a mixed drink, make sure to pre-mix a sizable amount in a pitcher so that you aren't stuck messing about with it when you ought to be having fun. Once the party begins, ask a close friend or helper to watch the drinks and refill when needed until it's finished. Follow suit with the non-alcoholic punch; people love to be given a task while socializing so they may share in the festive spirit.
On the punch front, whichever formula you go for (you can find plenty on the internet), avoid anything overly sugary – children present ought to have their own drinks – and should you have one, put aromatic bitters within reach (avoid adding any in the mix since they are not suitable for people who avoid drinks entirely). Put in some work with presentation so that the non-alcoholic option isn't perceived neglected; just spend a short time to add several pieces of citrus into the bowl.
In my view, I would avoid the store-bought trays of "party foods" that pop up at grocery stores during the holidays; they seem fussy, and usually involve turning the oven on (if you must go this route, remember that all guests secretly likes toasted bread or small hot dogs regardless). I'm convinced you can't beat two sizable containers with good-quality crisps (salted is universally liked), plus, provided there are no issues, some of those great-value containers of nuts available in the international aisle in stores, with perhaps some pitted olives for colour (try not to find pits in your pot plants next Easter).
In case, as my mother says, you don't consider crisps substantial fare, one large piece of tasty cheese on a platter with crackers and some artfully draped grapes always looks artistic. A platter featuring cured or cooked salami or salmon laid out on it (a single variety, unless you have a large budget), or a handsome ready-made tart, similar to that pop up in specialty sections seasonally, is more substantial, and you really will succeed with artisanal slices of focaccia, because they don't need spreading butter.
