Start with the Crowd-Pleasers

When you are feeding a room that spans three or four generations, the safest starting point is food that everybody already recognises. A grandparent, a teenager and a five-year-old may have very little in common, but they will all reach for a warm sausage roll. Familiar favourites do the heavy lifting at mixed-age celebrations because they need no explanation and no cutlery.

Build the core of your menu around these, and you give yourself a reliable baseline that will always be eaten:

• Mini sausage rolls and cheese and onion rolls, served warm rather than hot
• Chicken goujons or breaded strips with a yoghurt and mint dip
• Mini quiches and tarts in plain flavours — cheese, leek, ham
• Sandwiches cut into fingers, half on soft white and half on granary, with mild fillings
• Mini Yorkshire puddings filled with roast beef and horseradish, or with a vegetarian alternative
• Cocktail sausages, cheese cubes and pineapple, and a bowl of plain crisps

Keep the seasoning gentle and the portions small. A two-bite item suits a guest in a wheelchair, a guest holding a glass of wine and a guest who has already eaten lunch on the way over.

Balance the Board with Lighter Bites

Familiar food reassures, but a buffet made entirely of pastry will defeat older guests and anyone watching their appetite. Aim for roughly half of your spread to be lighter, fresher and easier to digest alongside the richer items.

• Crudités with hummus, tzatziki and a mild guacamole
• Falafel, halloumi skewers and marinated olives
• Tomato and mozzarella skewers, or melon wrapped in Parma ham
• Prawn cocktail or smoked salmon served in small glasses
• Stuffed peppers, roasted vegetable tartlets and grain salads
• Small cups of soup in winter, or chilled gazpacho in summer

These sit happily next to the sausage rolls and give guests who find fried food heavy something to fill a plate with. They also photograph well, which matters more than anyone admits at a wedding.

Cater for Children Without a Separate Menu

The temptation is to build a children's table entirely of beige food, but that tends to create a divide and leave the younger guests feeling exiled to a corner. A better approach is to make sure a good proportion of the main spread is naturally child-friendly, then add a few extras that small hands can manage.

Think plain pasta pots, cheese cubes, breadsticks, fruit skewers, cucumber sticks and small pots of yoghurt. Avoid anything with bones, shells, strong sauces or complicated wrappings. Set a low table or a sturdy box at child height so they can help themselves without an adult lifting them up, and keep drinks in lidded cups nearby. If a child has an allergy, treat that dish as seriously as you would for any adult guest — more so, because children are less likely to ask before eating.

Label Everything Clearly

Clear labelling is the single most considerate thing you can do at a mixed-age event. A guest with a gluten intolerance, a coeliac, a dairy-free teenager and a parent of a nut-allergic child all need the same thing: to know exactly what is in each dish without having to track down a member of staff.

Write a small card for every item that names the dish and lists the key allergens. Cover the fourteen regulated allergens — celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, peanuts, sesame, soybeans, sulphur dioxide and nuts. Add simple markers such as V for vegetarian, VE for vegan and GF for gluten-free, and place them where they can be read before the queue forms.

Beyond the cards, use a separate serving spoon for each dish, keep nut-based items at one end of the table with their own board, and brief whoever is carving or replenishing so they can answer questions confidently. If in doubt, leave the item out. No one will remember a missing dip; a guest will remember a reaction.

Set Up Stations so Guests Can Graze

A single long buffet creates a queue, and queues are where older guests give up and go back to their seats. Instead, spread the food across several smaller stations — a grazing table near the entrance, a hot station at the far end, a dessert table by the coffee, and drinks in the corner furthest from the doors. People move, mingle and eat in waves rather than all at once.

Small details make a real difference. Keep hot food above 63°C and cold food below 8°C, and don't leave anything out for more than two hours. Replenish in small batches so the table always looks generous but nothing sits wilting. Provide seating at a mix of heights, with a few chairs near each station for guests who can't stand for long, and put napkins and bins within easy reach.

Get the Quantities and Timing Right

For a drinks reception, plan on six to eight bite-sized pieces per guest for the first hour, then four to five for each hour afterwards. For a buffet main, allow three or four substantial items plus two sides per person, and two or three dessert bites. Add about ten per cent on top — running short is far more noticeable than having leftovers.

Stagger the food rather than putting everything out at once. Welcome bites when guests arrive, the main spread about an hour later, desserts after the speeches, and a small savoury or sweet bite around nine o'clock to carry the party through to the end. That rhythm suits every age group, keeps energy up and means nobody feels overfaced by a table groaning with food all evening.
